멀티레벨 H-bridge 인버터를 위한 새로운 carrierwave 비교 방식

A New Carrierwave-Based SVPWM for Multilevel H-bridge Inverter

In recent years H-bridge multievel inverters have been focused on and selected as the power inverter in several high voltage and high power application. This paper proposes an new PWM method for the multievel H-bridge inverter systems. The proposed PWM method is a carrierwave-based space vector PWM method which utilizes the phase voltage redundancies considering both the switch and conduction loss of the devices. We describe the new PWM method in detail and the effectiveness of the new PWM method is verified by the simulation results.
