Therefore, it is demonstrated that the shunt or series APF should be used for compensating the current or the voltage harmonic source.
从而说明对电流型或电压型谐波源进行谐波补偿，应该分别使用并联型或串联型apf。
Compared with the magnetic valve type controlled shunt reactor, the transformer type controlled shunt reactor is superior in its smaller harmonic current, faster respond speed and less power loss.
变压器式可控电抗器与磁饱和式可控电抗器相比，谐波电流更小、响应速度更快、功率损耗更小。
Based on the differences of harmonic testing point, there are two control ways for shunt active filters, that is, the way of load current sensing and the way of power supply current sensing.
并联型有源滤波器根据其谐波检测点的不同，有两种控制方法。即负载电流检测控制方法和电源电流检测控制方法。
