A SPWM Control Method for Dual Buck Half Bridge Inverter Based on the Direction of Inductor Current

Abstract:

The Dual Buck Half Bridge inverter has been widely researched because of no bridge arm shoot-through problem and higher efficiency. Because the switch frequency always varies, the output filter parameters are very difficult to optimally design by using hysteresis current control. In this paper, a SPWM control method is proposed. The control method not only can be easy realized, but also get the no-biased current model. Finally, the proposed SPWM control method is verified by the simulation and experiment results.
