Working Principle:

Active filters are parallel harmonic compensation device. It monitors the load current in real time with an external current transformer. The internal DSP calculates the harmonic content of the load current and sends the control signal to the inverter. The control inverter generates a harmonic current injected into the grid, which is equal to the harmonic current of the load and opposite direction, and realizes the active filtering function.
