The Active power filter monitors the load current real-time through the external current transformer CT, and extracts the harmonic component of the load current through the internal DSP computing, then sends it through the PWM signal to the internal IGBT, the inverter produces a current equal to the load harmonic and opposite to the harmonic direction and injects the current into the grid to compensate the harmonic current realizing the function of harmonic control.
