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.
