摘　　要：简要介绍了并联有源滤波器的原理及其普通滞环电流控制的特点 ,针对普通滞环电流控制方法的不足 ,提出并详细分析了一种最优电压滞环电流控制新方法。该方法的显著特点是通过识别参考电压矢量和电流误差矢量的区域控制滤波器的输出 ,避免了复杂计算和逆变器不必要的开关 ,并且快速、准确 。The work principle of shunt active power filter and the characteristic of common hysteresis current control method are introduced briefly.A novel optimal voltage hysteresis current control technique is suggested to overcome the defect of common hysteresis current control and analyzed in detail.Its notable strongpoint is that it avods the complicated calculation and unnecessary switching of voltage source inverter by identifying the locations of reference voltage vector and current error vector to control the filter's outputs.It is fast and accurate and improves greatly the performance of shunt active power filter.
