Abstract:
A power conversion apparatus characterized by comprising:a conversion section for rectifying and smoothing an AC voltage supplied from an AC power supply and converting the AC voltage into a DC voltage;an inversion section for converting the DC voltage prepared by conversion by said conversion section into an AC voltage and supplying the AC voltage to a load;a reactor series-connected to the AC power supply side in said conversion section, said reactor having an inductance of 4 to 20 mH;a booster for forcibly short-circuiting the AC power supply via said reactor; anda controller for controlling a short-circuiting conduction time of the AC power supply by said booster, within a range of 1.5 to 3.5 msec so as to optimize a power factor of the AC power supply.
