摘　　要：针对四桥臂变流器主电路,分析了固定频率的空间矢量脉宽调制电流控制方法和基于滞环比较的空间矢量脉宽调制电流控制方法,详细推导了两种方法的实现过程。仿真和试验结果表明,直流侧电压控制采用PI调节方式,有效地维持了直流侧电容的电压,保证了有源电力滤波器的正常工作。Aiming at the main electric circuit of four-bridge converter,this paper analyzed the fixed frequency space vector pulse width modulation （SVPWM） current control method and the SVPWM current control method which was based on he hysteresis comparison. The realization processes of two methods were deduced in detail. The simulation and experimental results show that the DC-side control adopts the PI regulating method to effectively maintain the DC-side capacitor voltage and ensure the normal operation of the active power filter（APF）.
