HENGYI ELECTRIC GROUP Complete set of HYAPF ac�ve power filter (abbreviated as ac�ve filter) 1 Brief introduc�on and schema�c diagram of filtering effect Wall mounted module HYAPF ac�ve filter can detect the loaded current in a real �me through the external current transformer, extrac�ng the harmonic components of the loaded current calculated by the internal DSP, and then deliver to the internal IGBT through PWM signal. The control inverter will produce current with the same size and opposite direc�on as the loaded harmonic and inject it into the power grid for compensa�ng harmonic current, thus to filter the func�ons. Harmonic compensa�on: APF can filter two to fi�y �mes of harmonic at the same �me. Reac�ve power compensa�on: Capaci�ve and induc�ve (from -1 to 1) step-less compensa�on Three phase unbalance compensa�on: Three phase ac�ve power unbalance compensa�on, Three phase reac�ve power unbalance compensa�on and phase compensa�on. The switching �mes of semiconductors can be over 10000 �mes per second, with quick response and instant management. The designed life�me can be over than 100 thousand hours (more than ten years).
