Abstract
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.
