摘　　要：当永磁同步电动机(PMSM)驱动系统采用二极管不控整流器提供直流电源时,能量不能双向流动,同时会给电网带来谐波污染。针对该问题,利用单相PWM整流器作为前端来构成PMSM背靠背驱动系统,并建立了整流器和PMSM的数学模型,确定了固定开关频率的滞环控制策略和基于转子磁场定向的PMSM矢量控制策略。并在此基础之上进行环路设计,以及通过实验验证了整个系统的能量双向流动和电机的四象限运行。When the DC power of permanent magnet synchronous motor drive system supplied by non-controlled rectifier,it can＇t satisfy the bi-directional energy transfer and also brings harmonic pollution to grid.To solve this problem,single -phase PWM rectifier was adopted as the front-end of the PMSM back to back drive system.The mathematical model of single-phase PWM rectifier and PMSM were established,and the control strategy of hysteresis current control under the fixed switch frequency and the vector control based on rotor field oriented were determined.Then,the loop design was describled.The bi-directional energy transfer and the performance of four-quadrant operation for motor were verified through experiments on the whole system.
