    Abstract: A power supply device for an electromotive railcar is adapted to receive external current from an overhead electric line via a pantograph and to feed driving current of lower voltage than the external current to electric loads in the railcar through first and second current output lines. The power supply device is provided with a static inverter couplable to the overhead electric line through first and second input lines and capable of producing the driving current. A battery is connected to the static inverter in parallel with the loads for selectively charging the driving current and discharging the charged electric current to the loads. An anti-discharge switch is provided on the first current output line for selectively connecting and disconnecting the loads to and from the battery. A discharge controller coacts with the anti-discharge switch for allowing the anti-discharge switch to be closed when no external current is fed to the static inverter and for causing the anti-discharge switch to become open when the static inverter receives the external current from the overhead electric line. In addition, the power supply device includes an emergency switch manually operable and in cooperation with the discharge controller for causing the anti-discharge switch to be closed so that the electic current stored in the battery is fed to the loads at the time the static inverter delivers no driving current to the loads.

    Abstract: A diesel-electric propulsion and operating system may be used alone or in combination with another power supply. It has particular application to a dual mode, trolley and diesel bus. The diesel engine is controlled to supply only that power demanded by the electrical systems, including the traction motor, and to operate on a fixed power curve. This provides an optimized efficiency. Other novel characteristics include a two-speed drive axle limited to the mode selector, a backup hydraulic motor and pump, a dual mode passenger compartment tester, and a diesel engine pretester.

    Abstract: A control device for an electric train formed of plural coupled carriages each of which receive power from an overhead power line via a collector, wherein each carriage is provided with a power converter for converting power from the overhead line to a suitable level for a load within the respective carriage. Each carriage also includes an auxiliary power supply device having an input coupled to the output of the power converter of the another carriage and an output coupled to an input of the power converter of the same carriage, so that if the power level from the overhead line to one carriage falls below a predetermined value, the power converter of that carriage is supplied with power from the power converter of another carriage through the intermediary of the auxiliary power supply device of the same carriage.
