摘要： To determine the timing of the electrical brake for completely stopping in electrical braking control, and also to achieve both sure stopping and good riding comfort in an electric vehicle powered by the motor by decreasing the braking force at a prescribed rate of change, the torque of the electric motor is controlled by controlling the power converter which powers the motor using a power converter controller. The deceleration of the motor is computed based on the detected speed of the electric motor which is as an output of the speed detection means, the subsequent speed of the electric motor is estimated based on the detected speed and the deceleration rate of the electric motor at the time the detected rotational speed of the electric motor falls below a prescribed speed, and torque control is carried out using an electric power converter controller, based on the estimated speed.

摘要： A drive system for a formation-train having an applied phase difference control comprises a main transformer 2 for stepping down AC electric power from a catenary 3, a plurality of power converters each having a converter 11 for converting AC power from the transformer 2 into DC power and an inverter 13 for converting the DC power into AC power, and a main electric motor 4 to be driven by power from the inverter 13, wherein the number of power converters in operation or the output thereof is altered on the basis of a threshold current limit from the catenary 3. Alternatively the number of operable power converters is decided on the basis of a threshold current limit from the catenary 3 and the power converter reduces power supplied to the motor 4 on the basis of the number of operable power converters. On the basis of an electric car performance at the power converters, either the number of converters in operation or their output may be changed.

摘要： A means for controlling a vehicle (e.g. a railway locomotive) driven by energy received intermittently from a source such as a catenary or third rail comprises a power storage system 7, an inverter 4 and a semiconductor switch 6. A DC voltage detecting means 9 measures the DC-side voltage of the inverter to determine whether the intermittent source is connected or not, and the charging or discharging of the power storage system through the inverter is controlled accordingly using the semiconductor switch. In this way the input voltage of the inverter is maintained within a predetermined operable range. A secondary battery DC voltage detector 11 may be provided to determine the terminal voltage of the power storage system. A charge/discharge control unit 13, inverter control unit 14, power storage control unit 16 and information transmission 17 means may also be provided.
