APF series active power filters are connected to the power system in parallel, and real-time sampling is performed through an external sampling loop.
Power system data, through the internal core computing chip of the equipment, analyze the harmonic component data in the system, and control
IGBT high-frequency switch, the output is equal to the magnitude and amplitude of the harmonic current in the system, and the current is opposite in direction, which has a negative impact on the harmonic current in the system.
The current is offset to achieve the purpose of controlling the harmonic current in the system.
