摘　　要：本文对由Buck/Boost双向变换器与双向半桥直流变换器构成的级联式双向DC-DC变换器的原理进行了分析,并研究了一种适用于Boost变换器的无源软开关电路。在数字控制的硬件平台之上,提出一端稳压和一端稳流的控制策略,可实现能量双向流动的自由转换。最后给出了实验波形.从而对理论分析进行了验证。Two-stage Bi-directional DC-DC Converter which was composed of Buck/Boost BDC and bidirectional Half bridge DCT was described,a novel reactive-soft-switching boost converter was also introduced in this article. An experimental prototype of bidirectional DC-DC converter controlled by DSP is designed. A novel control scheme adopting one port voltage regulated and another port current regulated is proposed to realize the energy conversion in bi-directional freely. In the last, experimental waves verify the theory.
