    摘要： A system corresponding to a plurality of different power sources (overhead contact line, power generator driven by engine, and fuel cells) is proposed as a method of using an optimum power supply in an electrified route and a non-electrified route. However, since different power converters are necessary for each power source, there are problems of an increase in the weight of a multi-car train, a reduction in the degree of freedom in composing a multi-car train because a mounting space needs to be reserved, an increase in the maintenance cost, a reduction in the reliability caused by an increase in the number of components, and the like. Provided are: a power conversion circuit that includes AC input ends, the number of which corresponds to the maximum number of phases among a plurality of different AC power supplies, and that converts AC power to a direct current; and switching means for switching a connection state of the AC power supplies and the power conversion circuit, wherein the connection state is switched according to the power supplies.

    摘要： When there is a restriction in an outfitting space, a mounted engine generator unit requires an operation restriction such as, for example, the current restriction of a generator if a sufficient heat capacity is not ensured. Therefore, this drive control device is provided with: a power conversion circuit for converting the AC power generated by the generator driven by an engine to a DC power; and a control unit for controlling the switching operation of the power conversion circuit on the basis of a switching operation mode. The control unit changes the switching operation mode in accordance with the rotational speed of the generator driven by the engine, thereby reducing and furthermore minimizing the percentage of the harmonic components of AC current for driving the generator.
