提出了一种多相准谐振（QR）零电流开关（ZCS）开关电容器（SC）双向DC-DC转换器结构，以减少电流纹波和开关损耗，并显着提高转换器效率和功率密度。这种方法提供了更精确的输出电压，以获得从双模式与半模式到n模式与1/n模式的电压转换比。这是通过添加不同数量的开关电容器和功率 MOSFET 开关以及用于正向和反向方案的小型串联谐振电感器来实现的。当所提出的转换器采用耦合电感器设计时，可以减小尺寸和成本。仿真和实验结果证明了具有和不具有耦合电感器交错式 QR ZCS SC 转换器的四相双向功率流控制应用的性能。演示了用于双向潮流控制应用的电池储能系统。
A multiphase quasi-resonant (QR) zero-current switching (ZCS) switched capacitor (SC) bidirectional dc-dc converter structure is proposed to reduce current ripple and switching loss, and significantly increase converter efficiency and power density. This approach provides a more precise output voltage to obtain voltage conversion ratios from the double-mode versus half-mode to n-mode versus 1/n mode. This is accomplished by adding a different number of switched capacitors and power MOSFET switches with a small series connected resonant inductor for forward and reverse schemes. The size and cost can be reduced when the proposed converter is designed with coupled inductors. Simulation and experimental results demonstrate four-phase with and without coupled inductor interleaved QR ZCS SC converter performance for bidirectional power flow control applications. A battery energy storage system for a bidirectional power flow control application is demonstrated.
