Abstract

The paper presents the performance analysis of multi-level inverter under various loading conditions. The multilevel topology proposed is series connected H-bride type and the modulation techniques are evolved to produce level shifted PWM in a way to get pulses with low component requirement to get the high level output. The THD analysis is also done for verifying the performance of the proposed topology. The designed topology of cascaded MLI is obtained for both single phase and three phase. The same loading analysis for THD is done for both single phase and three phase system. And the comparative analysis is done with reference to the conventional topologies.
