Three-phase digital generator

Abstract

The invention discloses a three-phase digital generator which is particularly applied to a three-phase non-equilibrium and non-linear load. The three-phase digital generator comprises an engine, a three-phase permanent magnet generator or three (three groups of three-phase generator windings), three three-phase rectifying and voltage-stabilizing modules, three DC / AC converters, three LC filters and a rectifier bridge. The three-phase digital generator is characterized in that the three-phase permanent magnet generator can be composed of a stator and a rotor or three stators and three rotors. The three-phase digital generator provided by the invention has the advantages that: (1) the three-phase digital generator is particularly applied to a three-phase non-equilibrium and non-linear load; (2) the volume and the weight of the three-phase digital generator are substantially less than the volume and the weight of a traditional three-phase generator, which can save a lot of copper materials, improve the efficiency, and save fuels; (3) the output voltage is stable; (4) the output harmonic is low and environmentally friendly; (5) an output power factor is controllable and can meet requirements of different loads; (6) three-phase output is symmetrical for any loads; and (7) three-phase output of the three-phase digital generator can also be used in a parallel manner by multiple machines to increase the output power.
