Abstract

See full text

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.
