Single phase input-3 phase full wave rectifier circuit and Single phase input pseudo-4 phase full wave rectifier circuit

摘要

The present invention provides a single-phase input-three phase full-wave rectifier circuit that lowers the cost and freely limits the range of power capacitors, and fundamentally the technical problems and improvements in conversion efficiency, overcoming power factors and power line harmonics, under DC load variations. Provides a small, lightweight single-phase input pseudo-4 phase full-wave rectifier circuit that maintains a constant voltage.;Single phase input-three phase full-wave rectifier circuit having the following characteristics: First: One input terminal of single-phase AC input terminal to one terminal of capacitor Connect natural terminal to one terminal of choke coil Different terminal of capacitor and other terminal of choke coil Make the third terminal by the connection of. Connection of the third terminal for the AC input terminal of two-phase AC input terminal and three-phase electric wave. Second: Equivalent three-phase determination by the choke coil's stir corresponding to the above-mentioned capacitor value and DC load resistance value of the DC output terminal. The wave circuit is constructed in which a three-phase full-wave rectified waveform is made.
