Problems solved by technology
[0002] With the development of the economy and the improvement of science and technology, the load types of generators are also changing. The existing generators are either single-phase generators, or three-phase generators, or three-phase generators with one-third of single-phase power generation. power, and the existing movable three-phase four-wire AC permanent magnet generators often have unbalanced load or even only need to use single-phase power when they are in use. The disadvantage is that the efficiency is significantly reduced. The three-phase generator only supplies single-phase power. In addition to the serious drop in power generation efficiency, its output power can only reach about 1 / 4 of the original generator's rated power.

The invention relates to the technical field of power generation, in particular to a switchable output single-phase-three-phase alternating-current permanent magnet generator system which comprises apower input unit, a variable-phase three-phase alternating-current permanent magnet generator unit, a servo execution unit and a power output and switching control unit. The power input unit is mechanically connected with the third end of the variable-phase three-phase alternating-current permanent magnet generator unit and provides power; the first end of the servo execution unit is mechanicallyconnected with the first end of the variable-phase three-phase alternating-current permanent magnet generator unit, and the second end of the servo execution unit is electrically connected with the first end of the power output and switching control unit. The second end of the variable-phase three-phase alternating-current permanent magnet generator unit is electrically connected with the second end of the power output and switching control unit; the third end of the power supply output and switching control unit outputs single-phase power or three-phase power. A damping winding of the alternating-current generator is omitted, energy consumption is greatly reduced, and total rated power output cannot be affected after single-phase-three-phase output is switched.
