POWER FACTOR COMPENSATION APPARATUS AND AIR CONDITIONER COMPRISING THE SAME

摘要

The present invention is connected to AC power supply unit and circuit, between one current sensing unit, it is used to feel the transient current for being supplied to circuit, it is connected between AC power supply unit and above-mentioned converter, circuit instantaneous voltage sense unit is put into for voltage detecting and to sensed current in current probe and the power factor of the circuit based on voltage, it is detected by voltage detecting unit and is related to the controller that power factor correcting comprises determining whether fast power factor.
