摘　　要：基于全钒液流电池(VRB)并网与离网运行的需要,设计了一种无源吸收的DC/DC变换器,避免了电路谐振对电池端的影响,并抑制了开关器件的开关电压尖峰。详细分析了电路工作原理,并设计了电路电流内环和电压外环控制器的参数。实验结果证明了无源吸收的DC/DC变换器设计的正确性。Based on the need of connecting and disconnecting to the grid of Vanadium redox batteries （VRB）, a full-br- idge DC/DC converter with a passive snubber is designed, which can eliminate the impact of VRB voltage caused by the resonance of DC/DC converter.Working Principle of this DC/DC converter with a passive snubber is introduced in detail, and the parameters of inner current loop and outer voltage loop are reasonably designed.The experimental re- sults verify the correctness of the design.
