本文探讨了一种双向DC-DC变换器应用于双电压电源系统，使用电池和超级电容器。该变换器由高频Transformer原边的MOSFET全桥拓扑和副边的电流反馈推挽拓扑组成。为了降低变换器低压侧的器件导通损耗，在超级电容器的充电和放电两种模式上均采用同步整流。此外，通过全桥的相移控制和推挽变换器中开关管的交叉导通占空比控制，实现了电池和超级电容器之间的宽范围电压调节。仿真结果表明，该电路拓扑实现了高效率的双向功率变换
This paper explores a bidirectional DC-DC converter applied for a dual voltage power system using a battery and supercapacitors. The presented converter consists of a MOSFET full bridge topology on the primary side of the high frequency transformer and a current-fed push-pull topology on the secondary side. To reduce the device-conduction losses in the low voltage side of the converter, synchronous rectification is employed on both modes of charging and discharging the supercapacitors. In addition, a wide range of voltage regulation between the battery and supercapacitors is realized by the phase shift control of the full bridge and the cross ON-duty control of switches in the push-pull converter. Simulation results shows that the proposed circuit topology realizes the bidirectional power conversion with high efficiency
