In this paper, we proposed the electric circuit using one common arm of H-Bridge Inverters to reduce the number of switching component in multi-level PWM inverter combined with H-Bridge Inverters and Transformers. and we proposed the switching method that can be same rate of usage at each transformer. Also, we tested the proposed prototype inverter to clarify the proposed electric circuit and reasonableness of control signal.
