In this paper the modulation strategies for single-phase multilevel PWM inverter with flying capacitors are analyzed. The analyzed strategies are: phase disposition PWM method, phase-shifted PWM method, the saw-tooth rotation PWM method and the carrier redistribution PWM method. The results are obtained through simulations by SimulinkTM.
