本文提出了一种新型三电平（3L）双向转换器（BDC）。与传统BDC相比，3L BDC的电感可以显着减少，从而使动态响应大大提高。因此，所提出的转换器非常适合燃料电池/电池混合动力系统。此外，所提出的转换器的开关上的电压应力仅为高压侧电压的一半，因此它也适合高压应用。详细介绍了控制电路的工作原理和实现。本文还提出了一种新颖的 BDC 双向软启动控制策略。构建了 1 kW 原型转换器来验证理论分析。
A novel three-level (3L) bidirectional converter (BDC) is proposed in this paper. Compared with the traditional BDC, the inductor of the 3L BDC can be reduced significantly so that the dynamic response is greatly improved. Hence, the proposed converter is very suitable for fuel-cell/battery hybrid power systems. In addition, the voltage stress on the switch of the proposed converter is only half of the voltage on the high-voltage side, so it is also suitable for high-voltage applications. The operation principle and the implementation of the control circuit are presented in detail. This paper also proposes a novel bidirectional soft-start control strategy for the BDC. A 1-kW prototype converter is built to verify the theoretical analysis.
