摘要

提出了一种新型的ZVS移相控制双向DC-DC变换器。它具有移相变换器的传统特性，包括恒定开关频率、零电压开关和通过移相控制电压。然而，新的变换器通过发展双向潮流能力和应用同步整流进行了改进，因此有源器件的导通电压降很小。因此，建议在电动汽车(EV)中使用。本文对所提出的变换器的电路工作原理进行了详细的描述，并进行了数学计算，并给出了实验结果来验证这一概念。

A novel square-wave converter with bidirectional power flow

A novel ZVS phase-shift controlled bidirectional DC-DC convertor is proposed. It possesses the conventional features of phase-shifted convertors, including constant switching frequency, zero-voltage switching (ZVS) and voltage control by phase-shift. However, the new convertor has been improved by developing a bi-directional power flow capability and applying synchronous rectification, hence the on-state voltage drop of the active devices are small. Therefore it is recommended for use in an electric vehicle (EV). In this paper, the principle of circuit operation of the proposed convertor was described in detail with mathematical calculations, and the experimental results were also given to verify the concept.
