A Single-Phase Current Source Solar Inverter with Constant Instantaneous Power, Improved Reliability, and Reduced-Size DC-Link Filter

A Dissertation Presented in Partial Fulfillment
of the Requirements for the Degree Doctor of Philosophy

Abstract
 This dissertation presents a novel current source converter topology that is primarily intended for single-phase photovoltaic (PV) applications. In comparison with the existing PV inverter technology, the salient features of the proposed topology are: a) the low frequency (double of line frequency) ripple that is common to single-phase inverters is greatly reduced; b) the absence of low frequency ripple enables significantly reduced size pass components to achieve necessary DC-link stiffness and c) improved maximum power point tracking (MPPT) performance is readily achieved due to the tightened current ripple even with reduced-size passive components. The proposed topology does not utilize any electrolytic capacitors. Instead an inductor is used as the DC-link filter and reliable AC film capacitors are utilized for the filter and auxiliary capacitor. The proposed topology has a life expectancy on par with PV panels. The proposed modulation technique can be used for any current source inverter where an unbalanced three-phase operation is desires such as active filters and power controllers. The proposed topology is ready for the next phase of microgrid and power system controllers in that it accepts reactive power commands. This work presents the proposed topology and its working principle supported by with numerical verifications and hardware results. Conclusions and future work are also presented.

Design of Inverter for LCD TV Backlight
with Flat Fluorescent Lamp

The liquid crystal display(LCD) TV market has been growing continuously and cost reduction is one of the biggest issues to increase its market share. The LCD needs backlight because it belongs to non emissive displays. The cold cathode fluorescent lamp (CCFL) and external electrode fluorescent lamp (EEFL) are widely used in backlight system for LCDs. But assembly of CCFL and EEFL backlight system is very complex. The flat fluorescent lamp (FFL) is a newly developed light source and it has a very simple structure. The LCD backlight can have a simple structure if the newly delvelop FFL is used as a light source. The backlight with FFL can be more cost effective than that of the backlights with CCFL or EEFL light sources. But the temperature behaviour of FFL backlights are different from the backlight with CCFL or EEFL light sources, which prohibits FFL backlight from being accepted as the backlight for commercial application.

Comparison of Simulation using PSIM and SIMULINK in Power Electronics Circuits SAMNANG KUONG

ABSTRACT

This thesis proposed the comparison of both simulation softwares PSIM and MATLAB/SIMULINK, implemented on the power electronics circuits. It will be helpful for designers to decide which software is preferable for the analysis of their power electronics circuits. The circuits that invoked to simulation are AC to DC converters(rectifiers), DC-DC converters, DC-AC converters(inverters), and AC-AC converters. The pure resistances and inductances load are used and input power is supplied by the single-phase and three-phase AC or DC voltage source. The comparison is focusing on the differences of output performances between these two simulation softwares, and the results are considered on the output waveforms of circuit which is drawn and simulated on the schematic window of each software; whether the waveforms in each circuit are matched or not. The process of comparison was accomplished on the same condition of both simulation softwares. The explanations and the features of these comparison is included.
