Zusammenfassung:The utility model relates to a single phase and three phase full voltage power supply converter, comprising a three phase bridge, a voltage detection circuit and two switches and characterized in that the three phase bridge rectifies inputted single phase or three phase voltage alternating current into direct current; a power supply input terminal is provided with a neutral line to respectively compose a first wiring terminal (A), a second wiring terminal (B) and a third wiring terminal (C) connected to a three phase power supply and a neutral line (N). The first wiring terminal (A) and the second wiring terminal (B) are meanwhile input terminals of a single phase power supply; the voltage detection circuit controls on and off combination of the two switches in dependence on a voltage scope of the input terminals and automatically adapts for a full voltage input scope. The single phase and three phase full voltage power supply converter has a reasonable design, and can automatically identify a single phase or three phase power supply type and adapt for a full voltage scope, thereby realizing the purpose of plug-and-play of electric appliance equipment and seamless application of different nations and regions, the versatility being good.
