摘要
电压源型有源电力滤波器直流侧电容电压的稳定程度对补偿性能有直接的影响.研究了有源电力滤波器、电源、非线性负载三者之间的能量交换机理,分析了变流器直流侧电容电压的稳定问题,并提出了用PI控制器维持直流侧电容电压稳定的方法.仿真结果验证了该方法的可行性.
The stability of the dc bus capacitor voltage is directly connected with the compensatory capability of an voltage source active power filter. The principle of energy commutation among APF, source and nonlinear load is studied, the stability of the dc bus capacitor voltage is analyzed and a method, using PI controller to maintain the stability of the dcbus capacitor voltage, is presented. The validity of this method is proved by simulation results
