We are offerng wanlida 300a active power filter which can dynamically filter harmonic with variable amplitude and frequency and compensate reactive power. apf technical principle active power filter (apf/ahf) is new power electronic equipment which can dynamically filter harmonic with variable amplitude and frequency and compensate reactive power, it overcome the shortages of conventional lc filter and obtained the better compensation performances than passive filter. the right diagram is schematic diagram of active power filter (apf/ahf), where, vs is ac power supply, nonlinear load is harmonic source, it generates harmonic and consumes reactive power. Apf system is composed of instruction current operational circuit and compensation current generation circuit, the instruction current operational circuit is mainly to detect current components in harmonic current and reactive power of compensation object, and the compensation current generation circuit generates equivalent compensation current with same amplitude and inverse polarity with harmonic current to filter harmonics according to instruction signal, the main circuit adopts pwm converter. apf functions reduce harmonic distortionimprove power factorreduce line lossprevent neutral line from overheatprevent power equipments from noise, overheat and vibration like motor, transformer etc. Prevent signal transmission equipments from data loss and interferenceprevent measurement error caused by non-sinusoidal current and voltage. Prevent sensitive semi-conductive device from damageprevent circuit breaker trip. Prevent capacitors from burn due to harmonic resonanceensure safety of power system and reduce energy consumptionapf technical features can filter all kinds of harmonic currentsfiltering capability >95% for aimed harmonictraction level igbt module, 20khz switching frequency response time
