Space Vector Pulse Width Modulation is popular for variable frequency drives. The method has several advantages over carried based PWM and is computation intensive. The implementation of SVPWM for multilevel inverter requires special attention and at the same time consumes considerable resources. Due to faster processing power and reduced over all computational burden, FPGAs are being investiga...

This paper presents a Selective Harmonic Elimination-PWM technology (SHE-PWM) employing H-Bridge multilevel inverter configuration. In this method variable DC voltage is used and the lower order harmonics are eliminated, without affecting the structure of the inverter. This method gives constant switching angle, so it reduces the number of steps required for offline calculation. The proposed me...

In this paper comparative study of proposed hybrid multilevel inverter (HMI) operating in modified pulse width modulation (PWM) mode with cascaded H-bridge multilevel inverter (CHMI) is done. Two types of HMIs are proposed with same configuration. To control the two HMIs, modified PWM techniques are derived from sinusoidal pulse width modulation (SPWM) to reduce the switching losses in the inve...
