摘要： A variable-gauge train control apparatus for a variable-gauge train having a gauge variable in a gauge conversion section includes: a plurality of main motors that transmits driving force to axles and wheels; a plurality of inverters that outputs voltage to at least one of the main motors; and voltage control units that control the individual output voltages of the plurality of inverters. Each of the voltage control units corresponds to one of the inverters and, when at least one of the axles to be subjected to the driving force controlled by the corresponding one inverter is within the gauge conversion section, controls the speed of the associated main motors by using, as a speed command value, a train speed converted into a rotational frequency.

摘要： 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.
