  • Publication number: 20220048544
    Abstract: A variable-gauge train control apparatus includes an inverter that collectively controls the torque of main motors; and a voltage control unit that controls an output voltage of the inverter. When at least one of axles to be driven by the main motors is within the gauge conversion section and at least one of the axles is located outside the gauge conversion section, the voltage control unit treats, as a reference frequency, a value obtained by conversion of an average value of rotational frequencies of the axles located outside the gauge conversion section into the electric angular frequencies of the main motors, and adds up a slip frequency command and the reference frequency to provide the frequency of the output voltage of the inverter.

  • Patent number: 10688878
    Abstract: A variable gauge train control device comprises an inverter, a location detector, and a torque calculator. The inverter collectively controls torques of main electric motors. The location detector detects an entry into a gauge changeover section. The torque calculator, upon detection by the location detector of the entry into the gauge changeover section, suspends idling control that otherwise restricts the torques of the main electric motors and calculates a first torque pattern for making the inverter operate in accordance with the torques of the main electric motors.
