摘要
针对双主动全桥DC-DC变换器输入和输出侧电压严重不匹配的问题,研究了宽电压范围双向DC-DC变换器,分析了其电压特性、电流特性和功率特性,研究了主电路参数的设计,并提出了一种分布式闭环控制与集中式电压平衡控制相结合的控制策略,结合了集中式控制和分布式控制的优点,具有简单有效、易于扩展不同级联数和电压等级的DC-DC变换器的优点,且具有良好的动态响应能力。在理论研究的基础上,研制了一台实验样机,并且通过实验验证了所提出控制策略的有效性。
To deal with serious voltages mismatching of DC-DC converter based on dual active bridge converter,the wide voltage range bidirectional DC-DC converter was studied.The voltage and current characteristics,and power transmission characteristic were analyzed,the main circuit parameters were designed,and a control strategy combining distributed closed-loop control with centralized voltage balance control was proposed.The control strategy combined the advantages of centralized control and distributed control,and it had the advantages of simple and effective,easy to be applied to high voltage DC-DC converter,and good dynamic response ability.On basis of this,a down sized prototype was built,and the experiments verify the correctness of the proposed control scheme.
