提出了一种用于电动汽车的双向DC-DC变换器。该变换器综合了开关电感和开关电容变换器的优点。该变换器具有较宽的电压增益范围、较低的功率开关管电压应力以及输入输出端接地点之间的共地。此外，该变换器还采用同步整流技术，在开关死区时间内实现零电压开关，提高了变换器的效率。推导了变换器的工作原理、稳态分析和各器件的电压电流应力。最后，设计了一台高压侧（400 V）恒压、极低压侧（24V）恒压的1 kW变换器，并进行了仿真。
In this paper, a Bidirectional DC-DC Converter (BDC) for the Electrical Vehicle (EV) application is proposed. The converter benefits the advantages of both switched-inductor and switched-capacitor converters. The proposed converter has wide voltage gain range, low voltage stress on the power switches, and common ground between the grounds of the input and output sides. In addition, synchronous rectification is utilized to achieve Zero Voltage Switching (ZVS) during turn on and turn off dead time, which enhance the efficiency of the converter. The operating principle of the converter, steady-state analysis, and all devices’ voltage and current stresses are derived. Finally, a 1 kW converter with constant high-voltage side (400V) and very low-voltage side (24V) has been designed and simulated.
