Propulsion Control Device

Abstract: This propulsion control device (80) comprises: a filter capacitor (6) that smoothes an overhead line voltage applied from an overhead line (1); an inverter (7) which is connected in parallel with the filter capacitor (6) and which applies a variable-voltage and variable-frequency AC voltage to a propulsion motor (8) mounted on a railway vehicle, and a control unit (12) that controls the inverter (7) on the basis of the overhead line voltage and the filter capacitor voltage. When the overhead line voltage exceeds a first threshold value during a regeneration operation of the propulsion motor (8), the control unit (12) carries out regenerative power control to lower, to below a command voltage, the motor applied voltage to be applied to the propulsion motor (8).
