Development of Three-Phase On-Board Battery Charger for PHEV without High-Capacity Electrolytic Capacitor Ying-hao, Zhang Department of Electrical Engineering Graduate School, Myongji University Advisor Professor Byung-Moon Han
A new two-stage on-board battery charger which can operate in both three-phase mode and single-mode is proposed for plug-in hybrid electric vehicles (PHEVs). It consists of three identical chargers which connect to battery in parallel, and each of them has a cascaded structure of high frequency resonant converter with a constant switching frequency for electrical isolation, and buck-boost converter for charging control and harmonic regulation of input current under wide range line-input voltage. This structure uses small link capacitors so that high-capacity electrolytic capacitors can be removed in automotive applications. An LLC resonant converter is proposed in the first stage. The parallel buck-boost converters operating in discontinuous conduction mode are employed in the second stage, so that the voltage stress of components could be reduced and the simple controller can be used to control charging current. Digital control of converter is realized by applying DSP (Digital Signal Processor) that performs constant current through duty control of buck-boost converter. Duty ratio of LLC converter is unregulated. Proposed Converter stably operates in various load condition (within 10kW) and it is proven that the proposed converter achieves efficiency of higher than 93% and power factor of higher than 0.99 through experiment..

WDS - Power Supply Design Software

Design stable analog and digital power supplies in minutes!
Stabilising a power supply using WDS could not be simpler. The user simply selects their topology and types in their input/output specification into WDS. The software will then automatically select the appropriate component values for this design. At any stage the user can change the component values away from those automatically calculated by WDS and enter the actual component value used in their design. From power stage component selection to poles, zeros and controller coefficients; our advanced PSU design software, WDS, will greatly simplify the task of designing a power supply whilst still keeping you in control at every stage of the process. WDS has been designed as the ultimate toolbox for the power supply design engineer. Designs and stabilises analog and digital PSU control loops in minutes Automatically calculates poles and zeros as well as component values of the worlds most popular topologies Sophisticated control algorithms stabilise digital power supplies with automatic coefficient calculations for floating point, 32 bit and 16 bit processors Special features allow manipulation of digital compensator coefficients for a host of micro-controllers Automatic compensator design for isolated power supplies with TLx431/LMx431 and a host of industry standard optocouplers Simulations in time domain, frequency domain and ability to superimpose real measurements on simulated data

Power electronic transformers for AC-AC and AC-DC conversion with reduced number of switches Castelino, Gysler Fatima (2013)

Autor Castelino, Gysler Fatima Data 2013-08
Type Thesis or Dissertation
Resumo In this research, a novel reduced-switch Power Electronic Transformer is proposed for three-phase power conversion (three-phase AC to AC as well as three-phase AC to DC). The goal of this project is to reduce the weight and size of the power converter by replacing the low-frequency transformers with high-frequency transformers (HFTs). The novelty of these proposed topologies is that they have only two controlled switches on the primary side of the high-frequency transformers. Additionally, these switches operate at 50% duty ratio, hence they are easy to control. Pulse Width Modulation (PWM) control is only necessary in the converters on the secondary side of the HFT. The modulation strategies proposed in this work achieve nearly Zero Current Switching (ZCS) for these two primary switches. In the proposed three-phase AC to AC Power Electronic Transformer, a Matrix Converter (MC) is employed on the secondary side of the transformer. Matrix converter with nine four-quadrant switches is a `more-silicon' and nearly capacitor-less solution for AC to AC conversion. This single-stage AC-AC converter without any electrolytic capacitors translates to higher reliability and efficiency. High-frequency transformers have finite leakage inductance, hence, any switching in the primary or secondary of the transformer requires commutation of the transformer inductive currents. This problem of leakage energy commutation and the required protection are studied in detail in this thesis. Other features of this converter are bi-directional power flow and power factor correction. The second Power Electronic Transformer is proposed for three-phase AC to DC power conversion. This converter operates on the Dual Active Bridge (DAB) principle wherein the transformer leakage inductance is used for power transfer. Hence, this converter does not suffer from problems associated with leakage energy commutation and additional snubber circuits are not required for this converter. The proposed modulation provides the advantages of unity power factor on the AC side, galvanic isolation and bi-directional power flow capability. Both these PETs have been analyzed and simulated. Laboratory prototypes have been built and tested to verify the advantages of the proposed PETs.
