Simulation Based on High Switching Frequency H-Bridge 5-Level Multilevel Inverter Using Level Shifted In Phase Disposition (IPD) Modulation

Analytical solutions of Pulse Width Modulation (PWM) strategies for multilevel Cascaded H-Bridge inverters are presented. These solutions show that the Phase Disposition (PD) PWM strategy for Cascaded H-Bridge Multilevel inverters are presented, When the carrier frequencies are adjusted to achieve the same number of total switch transitions for each inverter over one fundamental cycle. From this understanding, a method is proposed to apply the harmonically superior Phase Disposition (PD) PWM strategy for NPC inverters to Cascaded inverters, to achieve improved harmonic performance for the modulation of cascade inverters. Both theoretical and simulated results are compared and in this paper are archived result on a Simulation Based on High Swishing frequency H-Bridge Multilevel Inverter Using phase shifted Modulation using Matlab software.
