    • A control apparatus for controlling an electric vehicle, electric car, rolling stock and electric locomotives, which ensures that an inverter output frequency command for its inverter will not depend on the rotor frequency of the induction motor, but controls the inverter output current using a constant current control system, thus preventing an overcurrent, and is capable of accelerating or decelerating the vehicle at a torque precisely corresponding to a current command. The inverter output frequency command is incremented or decremented in accordance with a frequency-to-time rate-of-change command which has been updated by the current control system. Since the inverter output frequency command is adapted basically not to depend on the rotor frequency of the induction motor, and since the output current of the inverter is controlled by the constant current control system, there are such advantages according to the invention that an overcurrent is not likely to occur, and the vehicle can be accelerated or decelerated at a torque precisely corresponding to the current command.

    • The power converter of the invention relates to a small-sized highly efficient power converter for generating an a.c. voltage output of multiple levels with less harmonic content. In the power converter, a d.c. voltage source is separated into plural sections by series connected voltage dividing capacitors and multiple levels of a.c. output voltage are obtained from the divided d.c. voltage by on-off control of switching devices. The power converter has plural sets of the voltage dividing capacitors disposed separately adjacent to each switching devices, and series connection point of each set of the voltage dividing capacitors are connected to division points of the corresponding switching devices of each phase. The voltage dividing capacitors are connected with each other at their series connection points. Thereby, the arrangement makes wiring length short and equal between the switching devices and the voltage dividing capacitors for each phase and reduce a loss in the snubber circuit, resulting in an a.c. voltage output with less harmonic content.
