<P>PROBLEM TO BE SOLVED: To provide a traction inverter circuit. <P>SOLUTION: The traction inverter circuit includes a first energy accumulation device (12, 76) constituted so that DC voltage is outputted, a first bidirectional DC-AC voltage inverter (40, 104) coupled with the first energy accumulation device, and a first electromechanical device (60, 106). The electromechanical device includes a plurality of windings (64 to 68, 108 to 112) coupled with the bidirectional DC-AC voltage inverter. The traction inverter circuit includes a charging bus (80) having a first conductor (82) coupled with the windings of the electromechanical device. The charging bus (80) transmits charging current to the electromechanical device in order to charge the energy accumulation device through the electromechanical device and the bidirectional DC-AC voltage inverter, and receives charging current from the electromechanical device. <P>COPYRIGHT: (C)2010,JPO&INPIT |
