Abstract :
A number of modulation strategies are used in multi-level power conversion applications. This paper is focused on novel multi-carrier PWM methods which have been extended for use in cascaded H-bridge multi-level inverter. Novel multi-carrier PWM method can be optimized or balanced the switch utilization in cascaded H-bridge multi-level inverter. Five-level cascaded H-bridge multi-level inverter has been simulated and controlled with the novel multi-carrier PWM proposed in this paper to act as a voltage-source inverter (VSI)
