<P>PROBLEM TO BE SOLVED: To provide an AC voltage generator for generating an AC voltage by using two three-phase coils. <P>SOLUTION: A power output device 100 includes: motor generators MG1, MG2; inverters 20, 30; and a relay circuit 40. The motor generators MG1, MG2 include three-phase coils 12, 14, respectively. The inverter 20 periodically varies the electrical potential of the neutral position N1 of the three-phase coil 12. The inverter 30 periodically varies the electrical potential of the neutral position N2 of the three-phase coil 14 in a phase in which the phase of a variation is reversed in an electric potential of the neutral position N1. The relay circuit 40 electrically connects AC lines ACL1, ACL2 to a connector 50 in accordance with a control signal CNTL from a controller 60, and outputs an AC voltage Vac generated between the neutral positions N1, N2 to the connector 50. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
