HTAF active power filter

HTAF active power filter
Operation principle
HTAF active power filter is mainly consisted of instruction current arithmetic circuit and compensation current generating circuit. Instruction current arithmetic circuit monitors current in line on real time, changes analog current signal into digital signal, deals signal in DSP, divides harmonic and fundamental wave, sends drive pulse to impregnated current generating circuit in PWM form, drives IGBT or IPM power module, produces current with opposite polarity and same amplitude of compensating current and sends current into electrified wire netting, compensates or counteracts harmonic current and cancels electric harmonic actively. In this way, harmonic current is dealt actively, quickly and completely.
HTAF active power filter can supply required fundamental reactive compensating current, achieves dynamic reactive compensation and improves power factor of electrified wire netting.
