提出了一种无电流传感器的三相 PWM 整流器控制策略。系统采用双闭环控制，外环 PI 调节器控制直流侧输出电压，内环通过滞环调节器控制有功功率和无功功率，达到单位功率因 数运行的目的。根据整流器的数学模型通过电流重构可获得网侧电流，以实现无电流传感器控制。 仿真实验证明该方案具有良好的控制性能。(In this paper a current sensorless control strategy of three-phase PWM rectifiers is presented. Double close-loop control method is applied in the system. DC voltage is regulated by the external loop PI regulator. The system can operate at unity power factor by controlling the active and reactive power with two inner loop hysteresis controllers. The input AC current can be reconstructed the mathematical model of PWM rectifiers in order to eliminating current sensors . The simulation results prove that the system has good performance.)
