<P>PROBLEM TO BE SOLVED: To provide an inverter generator that can fully use the output of a generator and also easily increase or decrease the output of a selected AC by making it possible to selectively and surely output a three-phase AC or single-phase AC with a desired voltage and phase. <P>SOLUTION: An inverter generator comprises: a first, second, and third control unit 22a2, 22b2, and 22c2 which perform on-off control of switching elements of a first, second, and third inverter 22a, 22b, and 22c; a three-phase output terminal 26e series-connected to a U-phase terminal or the like and a single-phase output terminal 26f parallel-connected to the U-phase terminal or the like; and an engine control unit 28 which communicates the output of a change-over switch 30e to the first control unit and the like, and thereby makes a change-over mechanism 26g operate to output a three-phase or single-phase AC. The control units control on-off of the switching elements so that a three-phase or single-phase AC will be output corresponding to the output of the change-over switch, and also control on-off of DC conversion switching elements so that the voltage of AC output will become a target value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
