WANG, GANGYAO. Design, Development and Control of >13 kV Silicon-Carbide MOSFET based Solid State Transformer (SST).

 ABSTRACT
Within the advent of the smart grid system, the solid state transformer (SST) will replace the traditional 60 Hz transformer formed by silicon steel core and copper windings and provides the interface between the high distribution voltage and low utility voltage. Other than the smaller size and less weight, SST also brings many more functionalities including voltage regulation, reactive power compensation, power management and renewable energy integration. The motivation of this research is to design a solid state transformer based on the wide band-gap Silicon Carbide (SiC) power MOSFETs and compare it with the silicon IGBT based SST. With wider band-gap and higher critical electrical field, the high voltage SiC power device has advantages over silicon power device for both conduction and switching. An extensive study and characterization of the SiC MOSFET was first carried out. It has been found that the MOSFET parasitic capacitors store significant amount of energy and the MOSFET turn on loss is high but turn off loss is virtually zero with small enough turn on gate resistor. A method for estimating the MOSFET parasitic capacitances has been proposed and explained in detail. A PLECS loss simulation model has been developed for the >13 kV SiC MOSFET which has been verified through a boost converter with the SiC MOSFET switches under 40 kHz for both soft switching and hard switching conditions separately. Widely used full bridge circuit has been chosen as the topology for the SST rectifier for its simple structure and bidirectional power transfer capability. Form three different SPWM modulation methods, the bipolar single frequency SPWM method has been identified as the most suitable control algorithm for the >13 kV SiC MOSFET base rectifier. With such modulation method, the generated PWM voltage frequency equals to the switching frequency, the each MOSFET equivalent switching frequency under hard switching conditions is only 1/4 of the PWM voltage frequency. The SST rectifier efficiency has been simulated and measured for 6 kHz and 12 kHz switching frequency with 6 kV dc bus voltage and 3.6 kV ac voltage, which is 99.2% for 6 kHz with 8.8 kW load and 98.5% for 12 kHz with 8.3 kW load.

The SST DC-DC stage utilize the dual active half bridge (DHB) as the topology, its zero voltage switching (ZVS) turn on range has been analyzed and it is concluded that the dead-time and device parasitic capacitances will reduce the ZVS range while the magnetizing current will increase the ZVS range. Since the SiC MOSFET has very high turn on loss, it is desired to have ZVS for the full load range. The high frequency transformer with integrated leakage inductance for the DHB operation has been designed, the magnetizing inductance has been decreased for increasing the ZVS range. The DC-DC stage efficiency has been measured as 96.9% for 10 kHz switching frequency and 10 kW load, and the peak efficiency is 97.5% for 10 kHz switching frequency and 5 kW load.

AC-AC VOLTAGE REGULATION BY SWITCH MODE PWM CÛK VOLTAGE CONTROLLER WITH IMPROVED PERFORMANCE by Palash Kumar Banerjee - Ryerson University- Master of Engineering


AC-AC VOLTAGE REGULATION BY SWITCH MODE PWM CÛK VOLTAGE CONTROLLER WITH IMPROVED PERFORMANCE by Palash Kumar Banerjee 
 A project presented to Ryerson University in partial fulfillment of the requirement for the degree of Master of Engineering in the program of Electrical and Computer Engineering Toronto, Ontario, Canada, 2014

 ABSTRACT
Title: AC-AC Voltage Regulation by Switch Mode PWM Cûk Voltage Controller With Improved Performance
Degree: Master of Engineering
Year: 2014
Student Name: Palash Kumar Banerjee
Program: Electrical and Computer Engineering University: Ryerson University, Canada

In this research project, an AC Cûk voltage regulator has been proposed for maintaining constant voltage across the load during wide range of input voltage fluctuations. The proposed AC Cûk voltage regulator made of practical IGBT switches has been investigated for both manual and automatic control circuit. A fraction of the output voltage is taken as the input voltage of the control circuit and produce the error signal if any changes occur in the output voltage. The modified error signal is used to make PWM signals for switching devices as per output voltage of regulator. The PWM controls the ON/OFF time (Duty cycle) of switching devices (IGBTs) of the proposed regulator. As a result the regulator is maintaining a constant voltage across the load during any change in supply voltage. The simulation waveforms and the calculated total harmonics distortion (THD) values are compared with previously studied AC Buck-Boost regulator. The observed simulated waveforms of output voltage, output current and input current and THD values have been improved in case of proposed AC Cûk voltage regulator.

A High-Efficiency Isolated-Type Three-Port Bidirectional DC/DC Converter for Photovoltaic Systems Yu-En Wu and Pin-Nan Chiu Department of Electronic Engineering, National Kaohsiung First University of Science and Technology,Taiwan



A High-Efficiency Isolated-Type Three-Port Bidirectional DC/DC Converter for Photovoltaic Systems Yu-En Wu * and Pin-Nan Chiu Department of Electronic Engineering, National Kaohsiung First University of Science and Technology, Kaohsiung 824, Taiwan
 Abstract
This paper proposes a novel high-efficiency isolated three-port bidirectional DC/DC device for photovoltaic (PV) systems. The device contains a high step-up converter for PV modules to supply power to the DC bus, and a bidirectional charge/discharge control circuit for the battery with an improved boost-flyback converter. When the PV modules supply sufficient energy, their output can be stepped up and energy supply to the DC bus and charging of the battery can be achieved simultaneously. However, when the energy supplied is insufficient, the battery provides energy to the DC bus. When the proposed converter is operated in the step-down mode, the DC-blocking capacitor on the high-voltage side is used to reduce the voltage on the transformer and achieve high step-down performance. Moreover, to improve the overall efficiency of the system, the energy stored in the leakage inductance is recycled and supplied to the DC-blocking capacitor during operation in the step-up mode. Finally, to verify the feasibility and practicability of the proposed devices, a 500 W three-port bidirectional DC/DC devices was implemented. The highest efficiencies achieved for operation in different modes were as follows: high step-up mode for the PV modules, 95.2%; battery step-up mode, 94.2%; and step-down mode, 97.6%.

A PSR single-stage flyback LED driver with simple line regulation and quasi-resonant operation Nie Weidong(聂卫东) 1; 2; Ž, Yu Zongguang(于宗光) 1 , Wang Haibing(王海兵) 2 , Guo Bin(郭斌) 2 , Teng Long(滕龙) 2 , and Yang Lihang(杨力航) -Department of Electronic Engineering, Jiangnan University China



Abstract:
A single-stage flyback driving integrated circuit (IC) for light-emitting diodes (LEDs) is proposed. With an average primary-side current estimation and negative feedback networks, the driver operates in the boundary conduction mode (BCM), while the output current can be derived and regulated precisely. By means of a simple external resistor divider, a compensation voltage is produced on the ISEN pin during the turn-on period of the primary MOSFET to improve the line regulation performance. On the other hand, since the delay time between the time that the secondary diode current reaches zero and the turn-on time of the MOSFET can be automatically adjusted, the MOSFET can always turn on at the valley voltage even if the inductance of the primary winding varies with the output power, resulting in quasi-resonant switching for different primary inductances. The driving IC is fabricated in a Dongbu HiTek’s 0.35 m bipolar-CMOS-DMOS process. An 18 W LED driver is finally built and tested. Results show that the driver has an average efficiency larger than 86%, a power factor larger than 0.97, and works under the universal input voltage (85–265 V) with the LED current variation within 0.5%.

Abstract: 
This paper presents and implements a single-stage high-power-factor light-emitting diode (LED) driver with coupled inductors, suitable for streetlight applications. The presented LED driver integrates an interleaved buck-boost power factor correction (PFC) converter with coupled inductors and a half-bridge-type series-resonant converter cascaded with a full-bridge rectifier into a single-stage power conversion circuit. Coupled inductors inside the interleaved buck-boost PFC converter sub-circuit are designed to operate in discontinuous conduction mode (DCM) for achieving input-current shaping, and the half-bridge-type series resonant converter cascaded with a full-bridge rectifier is designed for obtaining zero-voltage switching (ZVS) on two power switches to reduce their switching losses. Analysis of operational modes and design equations for the presented LED driver are described and included. In addition, the presented driver features a high power factor, low total harmonic distortion (THD) of input current, and soft switching. Finally, a prototype driver is developed and implemented to supply a 165-W-rated LED streetlight module with utility-line input voltages ranging from 210 to 230 V.

Abstract
This paper presents a Pulse Width Modulation (PWM) controller and circuits for the high power LED (Light Emitting Diode) driver. The controller is available for the remote control through four major operation modes of ON, OFF, Emergency and Power saving using the serial communication. The entire driver circuits use a DC‐DC converter such a Boost topology with dimming, current, thermal control and communication functions for hallway lighting and automobile applications. According to the type and power of LED, a driver IC has already been developed and is produced. This driver IC makes the constant current and constant voltage available. However, if the LED driver allows delicate dimming control and thermal dissipation through allowance of LED off time, PWM control is needed. Therefore, a MCU (Microcontroller unit) for the PWM control as well as a driver IC for driving LEDs is needed. If this operation is embedded at this driver IC, the expense can be reduced. The LED controller integrated circuit (IC) was designed, simulated and fabricated in 0.35μm Magnachip/Hynix.

An Electrical Method for Junction Temperature Measurement of Power Semiconductor Switches- Baker, Nick -Aalborg Universy-DENMARK




An Electrical Method for Junction Temperature Measurement of Power Semiconductor Switches Baker, Nick Aalborg Universy-DENMARK 
 Dissertation submitted: April 6th 2016 PhD supervisor: Prof. Stig Munk-Nielsen Aalborg University, Denmark PhD
committee: Professor Josep Guerrero (chairman) Aalborg University Dr. Gernot J. Riedel ABB Cooperate Research Professor Philip Andrew Mawby University of Warwick PhD Series: Faculty of Engineering and Science, Aalborg University

Abstract
 Power semiconductor switches are critical components in power electronic converters and operate in thermally stressful environments. The junction temperature of a power semiconductor directly influences its power loss and is intrinsically linked to numerous failure mechanisms. Knowledge of this temperature is therefore important for optimal operation and for reliability reasons. If the junction temperature is known during the operation of a converter, real-time condition monitoring and active thermal control systems could be developed to improve system reliability. Performing direct measurements of junction temperature is difficult since the power semiconductor is generally encapsulated inside an array of packaging materials. Alternatively, the electrical behaviour of a semiconductor largely depends on temperature. If this relationship is known, the electrical parameters of the device can be monitored and used to estimate the junction temperature. These are known as Temperature Sensitive Electrical Parameters (TSEPs) and are one way to carry out non-invasive, real-time junction temperature measurements on fully packaged devices. Nevertheless, successful implementation of these techniques during the normal operation of a power semiconductor is thus far limited. Often holding back their use is the need to compensate for inherent fluctuations caused by a constantly changing electrical environment (or alternatively requiring interruption to normal operation to force fixed electrical conditions), and significant uncertainty over accuracy. As a result, this PhD aims to develop new methods, or improvements to existing methods, for junction temperature measurement via TSEPs during the operation of power semiconductor switches. In Chapter 1, the state-of-the-art in the topic of junction temperature measurement is introduced. A literature review of TSEPs investigated for use in operating power semiconductor switches is then provided. From this, several implementation issues are identified and used to formulate technical objectives for the PhD thesis. Chapter 2 introduces the first original contribution of the thesis. Two TSEP-based methods for junction temperature measurement, unpublished in scientific literature before the commencement of the PhD, are presented. The measurement principles are explained, and experimental validation is provided on Insulated-Gate-Bipolar-Transistors (IGBTs). The foremost advantages in the presented TSEPs are that they are measured without interruption to normal IGBT operation, and do not require compensation for varying load current conditions. The primary method presented is referred to as the Peak Gate Current (IGPeak) method, which is selected for further examination in Chapter 3. In Chapter 3, the second scientific contribution of the thesis is provided. Here, the accuracy of the IGPeak method on IGBTs is extensively examined using direct measurements of junction temperature from an Infra-Red camera. The validation is performed on IGBT dies with differing geometry, as well as IGBTs in both healthy and degraded conditions. Finally, IGBTs in a paralleled configuration are investigated. These results in terms of accuracy are compared with a traditional TSEP method commonly found in prior art.

Graduate school Wonkwang University
Abstract
Currently, road lightings are installed with less than 400W of existing metal halide lamps. These road lightings are being replaced by energy-saving lightings. Induction lamps are expected to be more actively replaced with targets for tunnel lighting and high ceiling lighting. Therefore, it is necessary to develop high efficiency, high power induction lamps system. In this study, the discharge tube design, lmap gas, lighting circuit, and lighting fixture were designed for the high power of the induction lamps. And Induction lamp system was optimized through electrical, optical, thermal characteristics analysis and simulation. For the development of the high power induction lamp, the induction lamp was fabricated according to the design factors such as gas type, gas pressure, discharge tube, ferrite core size, amalgam, and driving frequency after the improvement of the existing process.

In addition, the design and manufacture of the lighting circuit for the high power induction lamp were carried out. The light distribution characteristics through the optical design of the lighting fixture were compared and analyzed, and the illuminance distribution characteristics were simulated to develop the optimized high power induction lamp system. The discharge tube size of the high power induction lamp was 62mm, and the gas was optimized to Kr 100% and gas pressure 300 ~ 350[mmHg]. When the indium amalgam was applied, the induction lamp maintained the same power. As a result, optimization of the induction lamp, lighting circuit, and lighting fixture was completed in accordance with the rating. The characteristic analysis through the design of the lighting circuit for the induction lamp proceeded to improve and supplement. Based on the optical characteristics of the induction lamp and the system effect according to the driving frequency of the lighting circuit, the driving frequency was optimized to 135kHz. An optical simulation was performed according to the distance between the lamp and the reflector by using the OptisWorks program. and illuminance simulation was performed for each height according to the light distribution by using the Relux program. As a result, the high power induction lamp high ceiling fixture was completed.

In conclusion, Based on the high power induction lamp, ligthing circuit, lighting fixture optimization study was to present a guide for design and evaluation of induction lamp system. It is expected to be applied to additional induction lamp research and development in future.

 Abstract
One of the key enabling technologies behind many global megatrends, which are a ecting our lives as individuals and as a society in many different areas, is power electronics. Prominent examples are the shift from conventional energy sources to renewable energy sources, the reduction of greenhouse gas emissions due to the electri cation of mobility, and the trend towards cloud-computing in the information technology area, which are all based on the development of cost-e ective, e cient and compact power electronic systems. In order to ful ll future requirements for power electronic systems, it is therefore of great importance to identify new ways to develop systems with higher e ciency, power density, and reliability.

 The analysis of relevant literature reveals, that improvements of power electronic systems are to a great extent either based on the improvements of speci c components or on the modi cation of known control algorithms and/or topologies. These improvement processes, however, are of evolutionary nature and are not going to provide significant steps of performance improvements compared to today's solutions for the foreseeable future.
