摘　　要：为解决三相电流型PWM整流器的拓扑结构带来的系统阶次增加、并联谐振等问题,详细介绍了三相CSR的空间电流矢量的控制方法,包括系统的数学建模、控制策略、信号发生和实现调制等。在Matlab/Simulink软件平台进行了三相CSR双闭环解耦SVPWM控制方法的仿真,并通过与传统的SPWM控制方法进行对比,验证了该控制方法具有更好的动、静态特性,且动态响应快,能有效抑制网侧谐波,实现单位功率因数运行。该方法为三相CSR的控制方法提供了新思路,具有一定的理论和实际应用价值。In order to solve the problems of the topological structure of three - phase current source type PWM rectifier, e. g. , increasing tile system orders, and parallel resonances,etc. , the space current vector control method for three - phase CSR is introduced in detail, including mathematical modeling of the system, control strategy, signal generation and modulation implementation. The simulation of three - phase CSR double closed loop decoupling SVPWM control method is conducted on Matlab/Simulink software platform, and through comparing with ~aditional SPWM control method,the control method proposed possesses better dynamic and static characteristics,and the dynamic response is faster; it effectively suppresses harmonics to achieve unit power factor operation. The research provides new concept for three - phase CSR control method,if possesses theoretical and practical values.
