Multilevel inverter is one of the attractive topology for dc to ac conversion. Multilevel inverter synthesizes desired voltage wave shape from several levels of DC voltages. Though multilevel inverter has a number of advantages it has drawbacks in the vein of higher levels because of using more number of semiconductor switches. This may leads to vast size and price of the inverter increases and also leads to complex control. The new multilevel inverter with reduced number of switches overcome this problem and is well suited for high power applications. Multi carrier PWM technique is used for sine wave generation. PODPWM with optimization of carrier using absolute sine reference signal is used for control.
