| 摘 要： | 介绍了一种双PWM变频器系统的控制策略．在PWM整流侧采用空间矢量的无电压传感器的虚拟磁链的直接功率控制和在PWM逆变侧采用无速度传感器的矢量控制．这些控制策略使系统保持了很好的动态响应和静态特性．仿真结果表明本系统有良好性能．从PWM逆变侧到PWM整流侧增加的功率环提高了功率能量流动的动态特性，使输入和输出能量匹配从而减小直流侧电容的大小．

| Abstract: | A control strategy for PWM rectifier-inverter system is proposed.Non-line voltage sensors virtual flux based direct power control with space vector modulation for PWM rectifier and non-speed sensor vector control technology for PWM inverter are adopted.These strategies lead to good dynamic and static behavior of the proposed system.The results obtained in simulations show good performance of the proposed system.Additional power loop from PWM inverter side to PWM rectifier side improved dynamic behaviors of the power flow control.As a result,better input-output energy matching allows decreasing the size of the DC-link capacitor. |
