摘要
储能的发展对双向DC/DC变换器的传输效率有较高的要求,为此提出一种基于最大传输功率的双向全桥DC/DC变换器扩展移相控制策略,并采用奇异摄动法建立了扩展移相控制下变换器的小信号模型。最后,基于MATLAB/Simulink搭建仿真模型,仿真实验结果验证了该策略的有效性和可行性。
The development of energy storage requires high transmission efficiency of bidirectional DC/DC converter.Therefore,an extended phase-shifting control strategy of bidirectional full bridge DC/DC converter based on maximum transmission power is proposed,and the small signal model of the converter under extended phase-shifting control is established by using singular perturbation method.Finally,the simulation model is built based on MATLAB/Simulink,and the effectiveness and feasibility of the strategyis verified bythe simulation results.
