Abstract

The cascade H-bridge multilevel inverter has lesser harmonics as well as switching stress compared with diode clamped and flying capacitor multilevel inverter, But cascaded H-bridge multilevel inverter has more number of power switches required for multilevels. Hence more number of power switches leads greater heat losses, large in size, higher in cost and huge gate circuitry. The proposed structure contains less number of power switches and less harmonics in the output voltage than compared to cascaded H-bridge multilevel inverter. In order to get lesser hormonics and quality in the output waveform by the different PWM startegies. The different PWM strategies are, In-Phase Disposition Level-shift PWM(IPDLS-PWM), Anti-Phase Disposition Level-shift PWM(APDLS-PWM), Carrier Overlap Level-shift PWM (COLS-PWM) and Variable Frequency Level-shift PWM(VFLS-PWM) has been done. The results are verified through simulation study in MATLAB/Simulink in order to select the best PWM startegy, which provides less ripple(THD) in the output wave. An LC filter has been designed to eliminate the ripples and improve the harmonic profile.
