A Control Method of Dual Buck Half Bridge Inverter Based on the Phase of Voltage Loop Output

In this paper, a novel hysteresis current control method based on the phase of the output of voltage loop by using a single LEM current sensor is proposed. Because of having two filter inductors, the Dual Buck Half Bridge Inverter has on bridge arm shoot-through problem. Each inductor current can be independently controlled, so the power switches and the free wheeling diodes can be optimally chosen, and the efficiency of the inverter will be increased. So the inverter can promise high practical value in the engineering application. Finally, the control method is verified by simulation and experimental results.
