Abstract :
A new three-level PWM inverter is proposed. Its phase voltage is twice as high as that of the conventional neutral-point-clamped PWM inverter and a three-level waveform can be achieved without the switch voltage unbalance problem. Furthermore, its average neutral point potential is zero. The proposed inverter is verified by the PSpice simulation and experiment.
