Abstract :
H-bridge multilevel inverters have been focused on and selected as the power inverter in several high voltage and high power applications. This paper proposes a new pulse width modulation (PWM) method for the multilevel H-bridge inverter systems. The proposed PWM method is a carrierwave-based space vector PWM method that utilizes the phase voltage redundancies of the inverter to make both the switch and conduction loss of the devices equal one another. The new PWM method is described in detail and the effectiveness of the new PWM method is verified by the simulation and experimental results
