ABSTRACT
Now a day’s industrial applications need high power equipment for conversion of power. At medium voltage applications, to associate one and only power semiconductor switch directly could be a not much productive concept. To conquer this multilevel power converter structure has been presented and concentrated on as an elective in high power and medium voltage applications. Renewablesources like photovoltaic, wind, fuel cells are often handily interfaced to a multilevel converter for high power applications. This paper discussing about PUC converter which is the most advanced topologies of all multilevel converters and having a merit of reduced device count. A comparison is going to be shown for 7, 15, 31 levels of PUC converter with different loads in terms of TotalHarmonic Distortion(THD)%. The simulations are performed by using MATLAB/Simulink software.
