摘　　要：提出一种用于双电机传动系统的高频链(HFL)间接矩阵变换器(IMC)九开关逆变器拓扑,解决了传统IMC九开关逆变器电压传输比低的问题,同时具有功率密度高、传输损耗低、能够实现输入输出级电气隔离的优点。提出了用于HFL IMC九开关逆变器的半周期双极性空间矢量调制策略和双逆变器输出的分层控制策略,实现了零电流换流的同时也扩大了变换器的应用范围。仿真结果验证了控制策略的正确性和有效性。A high-frequency link(HFL)indirect matrix converter(IMC)nine-switch inverters topology for dual motor drive system is proposed.It solves the problem of low voltage transfer ratio of traditional IMC nine-switch inverters,and has the advantages of high power density,low transmission loss and electrical isolation of input and output stages.A half-period bipolar space vector modulation strategy and a layered control strategy for the output of the dual invert-er are proposed for the HFL IMC nine-switch inverters,which can realize zero current conversion and expand the ap-plication range of the converter.The simulation results verify the correctness and effectiveness of the control strategy.
