REPLACEMENT SHEET27 Date: 06 MAR 1996SINGLE PHASE INPUT-THREE PHASE FULL BRIDGE RECTIFIER CIRCUITAND SINGLE PHASE INPUT PSEUDO FOUR PHASE FULL BRIDGE RECTIFIERCIRCUITA B S T R A C TThe present invention proides Single phase input-Three phase full bridgerectifier circuit lower increase of cost and limitation free of power capacityrange, and provides small and light weight Single phase input-Pseudo four phasefull bridge rectifier circuit which keeps the constant voltage under the DCload variations, by overcoming the technical problems and improving radicallyconversion efficiency, power factor and power line harmonic.Single phase input-Three phase full bridge rectifier circuit having thefollowing characteristic process:First :Connect one input terminal of a singlephase AC input terminal with one terminal of a capacitor, and connect anotherterminal with one terminal of a choke coil. Make the third terminal byconnecting another terminal of a capacitor and another terminal of a chokecoil.Connect 2 single phase AC input terminals and the third terminal with theAC input terminal of a 3 phase full bridge.Second:By fixing the value of the above-mentioned capacitor and choke coilcorresponding to the DC load resistance value of a DC output terminal,an equivalent 3 phase rectifier circuit is composed, whereby, 3 phasefull bridge rectifier waveform is made.Fig. 9A & 9B
