Claim Text:
1. A propulsion control apparatus of an engine hybrid railroad vehicle comprising: a generator driven by an engine; a power storage device functioning as a direct-current-power supply source configured to be connectable to a direct-current common section; first and second power converters each of which is configured to be connectable to the direct-current common section, when direct-current power from the direct-current common section is input from a first input/output end side, operates as a DC/AC converter to output desired alternating-current power from a second input/output end side different from the first input/output end, and, when alternating-current power is input from the second input/output end side, operates as an AC/DC converter to output desired direct-current power from the first input/output end side; a plurality of motors divided into a first motor configured to be drivable by both of the first and second power converters and a second motor configured to be drivable only by the first power converter; a group of switches that switches an electric connection destination of the generator from the second input/output end side of the second power converter to the second input/output end side of the first power converter or switches an electric connection destination of the first motor from the second input/output end side of the first power converter to the second input/output end side of the second power converter; and a control unit that controls operations of the first power converter, the second power converter, and the group of switches according to operation forms of the first and second power converters.
