有源滤波器/柜模块通过外部电流互感器CT，实时检测负载电流，通过内部DSP计算来提取出负载电流的谐波成分。然后通过PWM信号发送给内部IGBT，控制逆变器产生一个和负载谐波大小相等、方向相反的电流注入到电网中来补偿谐波电流，从而实现滤波的效果。
The active filter/cabinet module detects the load current in real time through an external current transformer CT, and extracts the harmonic components of the load current through internal DSP calculation. Then, the PWM signal is sent to the internal IGBT, and the inverter is controlled to generate a current with the same magnitude and opposite direction of the load harmonic injected into the power grid to compensate the harmonic current, thereby realizing the filtering effect
