In this paper, a new 9-level inverter employing switched capacitor technique is proposed. Three bidirectional voltage blocking switches are employed to connect the four H-bridges and to incorporate the three switched capacitors. The proposed multilevel inverter (MLI) circuit outputs a 9-level waveform with a maximum boosting factor of four. Unlike the already established switched capacitor based MLI consisting of two stages the proposed MLI is single stage inverter. The switches in the proposed MLI is subjected to a low value of voltage stress equal to Vdc. The proposed MLI is further analyzed by using various multicarrier sinusoidal PWM technique such as Phase Shift PWM (PSPWM), Phase disposition PWM (PDPWM), Phase Opposition Disposition PWM (PODPWM), Alternate Phase Opposition Disposition PWM (APODPWM) and Variable Frequency PWM (VFPWM).
