摘要： The present invention discloses a power apparatus with the output voltage thereof made variable, which allows harmonics to be suppressed while an enhanced power factor being maintained. The power apparatus comprises an alternating current power source, a bridge rectifier circuit to subject alternating currents from the alternating current power source to full-wave rectification, a reactor connected between the alternating current power source and the alternating current input end of the bridge rectifier circuit and a capacitor connected via a bi-directional switch between the alternating current input end and the direct current end of the bridge rectifier circuit, further comprising a smoothing capacitor, a zero-crossing detecting means, a bi-directional switch drive signal generating means and a bi-directional switch driving means.
