Product Description

Rongzhi Active Harmonic Compensation Filter Basic principle

Active power filter (APF) is a new type of power harmonic control special equipment made of modern power electronics technology and digital signal processing technology based on high speed DSP devices. It consists of two main parts: command current operation circuit and compensation current generation circuit. The command current operation circuit monitors the current in the line in real time, converts the analog current signal into digital signal, and sends the signal to the high-speed digital signal processor (DSP) for processing, separates the harmonic wave from the fundamental wave, and sends the driving pulse to the compensation current generating circuit in the form of PWM signal to drive the IGBT or IPM power module. A compensating current with the same amplitude and opposite polarity as the harmonic current in the power grid is generated and injected into the power grid to compensate or cancel the harmonic current and actively eliminate the power harmonic.
