Analysis of 15 Level Inverter Using Hybrid PWM Strategy

Abstract

This paper represents a new topology 15 level asymmetric multilevel inverter with HYBRID PWM strategy. Multilevel inverter is triggered using hybrid PWM strategy. It includes Phase Disposition (PD) strategy, Alternate Phase Opposition Disposition (APOD) strategy and Carrier Overlapping (CO) strategy. The performance measures like Total Harmonic Distortion (THD), V_RMS (fundamental), crest factor, form factor and distortion factor are evaluated for various modulation indices. Simulation is performed using MATLAB-SIMULINK.
