摘要（英）：

The utility model discloses an active power filter comprising a power grid. The power grid is in electric connection with a load portion through a current acquisition apparatus. The current acquisition apparatus is in electric connection with a controller through a signal processing circuit. The controller is in electric connection an inverter circuit composed of symmetrical bipolar transistors through an IGBT drive circuit. The two ends of the inverter circuit are in parallel connection with an inductance capacitance branch and an inductance branch. The inverter circuit forms a loop through a direct current PT. An output of the inverter circuit is connected into the power grid in a coupling mode through an inductor. According to the active power filter of the utility mode, compensation can be carried out on a reactive power through the inductance capacitance branch and the inductance branch. Furthermore, the active power filter can effectively adjust a three-phase current to balance the three-phase current through cooperation between the controller and the inductor.
