    摘要： There is provided a control apparatus of an AC motor (2) capable of performing stable torque control even over the entire running region of the AC motor. Structurally, a feedback control system (9, 8) for controlling the magnitude of motor primary current, a feedback control system (8, 17) for controlling the exciting component of motor primary current and a feedback control system (8, 18) for controlling the torque component of motor primary current are provided. Torque control is effected by a vector control system (4, 5, 6, 7, 8, 9) in the low speed running region and torque control is effected by a slip frequency control system (16, 10, 19, 20, 21, 22, 23) in the high speed running region, so that torque can be controlled excellently over the entire running region.

    摘要： The invention provides a railway vehicle comprising a switching device and an electric storage device, and when contact break between an electric power line and a power collector occurs, the switching device is activated to perform charging or discharging of the electric storage device, wherein after the vehicle recovers from the contact break state, the switching device is stopped so as to cut down fruitless consumption of energy. The control system of an electric vehicle comprises a switching signal output device composed of a DC voltage detector for detecting a voltage value of a power converter for controlling the operation of a main motor and a contact point of the switching device, a travel distance computing device for computing a travel distance of the main vehicle, and a contact break position database storing in advance the position in which contact break occurs, wherein the device predicts entry of the vehicle in a section where contact break occurs by verifying the travel distance value and the contact break position database, and outputs a switching signal. The switching device is activated or stopped based on the switching signal.

    摘要： In conventional techniques, it is necessary to use a storage element having a large capacitance such as a lithium-ion battery and there are the problems of reduction in capacitance and cost of the system. Using a capacitor as a storage element, a path of a current flowing in a direction in which the capacitor is discharged is provided by a charge/discharge device in addition to a path of a current flowing in a direction in which the capacitor is charged by a high speed-range electric braking function, whereby a current corresponding to a difference in potential between a regenerative current (current flowing in the direction in which the capacitor is charged) and a chopper current from the charge/discharge device (current flowing in the direction in which the capacitor is discharged) is made to flow in the capacitor 7.
