Implementation of Cascaded H Bridge Inverter Using Space Vector PWM

SUGI V, CHANDLA ELLIS

The modulation and control strategies plays vital role to minimize THD in Multilevel inverter .The modulation technique includes Sinusoidal Pulse Width Modulation (SPWM), Selective harmonic Elimination and Space Vector Pulse Width Modulation (SVPWM).Multilevel inverters has tremendous application in the area of high-power and medium-voltage energy control. In this paper simulation of SVPWM is performed for cascaded H bridge inverter . Simulation of three level, five level and seven level cascaded H bridge inverter with Space vector PWM has been carried out. Implementation and simulation of SVPWM inverter are presented to realize the validity of the SVPWM technique.
