[Problem] To propose a control apparatus for an electric train, in which the regenerative energy of a DC power feed circuit can be consumed without disposing the brake chopper or electric-double-layer capacitor of the DC power feed circuit. [Means] A control apparatus for an electric train according to this invention includes an AC electric motor which drives the electric train, and a variable-voltage variable-frequency inverter which controls the AC electric motor, and further includes an auxiliary power source device connected to a DC power feed circuit, and load control means for controlling a load connected to the auxiliary power source device, wherein the load control means receives an inverter state signal representative of an operation state of the variable-voltage variable-frequency inverter from the it, and the load control means controls the load in accordance with the inverter state signal. Besides, the control apparatus for the electric train includes detection means for detecting DC power feed information representative of the DC power feed state of the DC power feed circuit, and the load control means controls the load in accordance with the DC power feed information.
