摘要
在传统单相DC/DC变换器及基于Yd连接的三相DC/DC变换器的基础上,对基于Yd连接的三相DC/DC变换器拓扑结构进行了理论分析,并采取相应的控制策略抑制因三相电感存在差异导致的三相电流不平衡,最后搭建了实验平台,验证了理论分析的正确性和该拓扑结构的可行性。
Based on the traditional single-phase DC/DC converter and three-phase DC/DC converter with Yd-connec-tion, it analyses the topological structure of DC/DC converter based on three-phase transformer utilizing Yd-connectionin theory.Then,the corresponding control strategy to solve the three-phase current unbalance problem as a result ofthree-phase inductance differences is applied.The experimental results show the correctness of the theoretical analysisand the feasibility of topological structure.
