Effective loss reduction analysis in new switched-capacitor boost-multilevel inverter using series/parallel conversion

An switched capacitor multi-level inverter gives higher voltages than the input dc voltage with help of series-parallel conversion operation. In this paper we are finding out from the various methods of multi-level inverters to reduce total harmonic distortion (THD) voltage in bus output of inverter as well as reduction of switching frequency ultimately overall improvement in efficiency of inverter. Also this inverter can reduce need of input step up dc voltage converter system as well as output side transformer or inductors to reduction of overall size of inverter. All results are obtained using MATLAB (SIMULINK) also theoretical results are calculated and verified with simulated results.
