摘　　要：随着风力发电和光伏发电技术的快速发展,基于电网能量的储能系统开发和研究越来越受到大家的关注,提出了一种双半桥双向直流变换器,并给出了相应的移相控制策略,对正向升压和反向降压两种工作模式下的稳态工作性能进行仿真验证,并设计了实验样机,验证了双半桥双向直流变换器的工作模态及控制策略,仿真及实验结论表明:双半桥双向直流变换器在经历负载突变和输入电压突变过程中,能够快速的恢复稳态,实现微电网的实时调节。With the rapid development of wind power and photovohaic power generation technology, energy storage systems based on grid energy research and development lead to more and more people＇ s attention, a two-way dual half-bridge DC-DC converter, and the corresponding shift control strategy are presented, the steady-state performances of the forward and reverse boost buck of two modes of operation are carried out under simulation and experimental prototype is designed to verify the dual half-bridge bidirectional DC converter operating modes and control strategies. The simulation and experimental results show that two half-bridge DC-DC converter in a two-way experience mutation load and input voltage mutation process can quickly restore homeostasis and achieve real-time adjustment mierogrid.
