<p>[PROBLEMS] To provide an electric car control apparatus capable of consuming a regenerative energy of a DC feeding circuit without providing any electric double layer capacitor or any brake chopper for the DC feeding circuit. [MEANS FOR SOLVING PROBLEMS] An electric car control apparatus has an AC electric motor for driving the electric car and also has a voltage-variable, frequency-variable inverter for controlling the AC electric motor. The electric car control apparatus further has an auxiliary power supply apparatus connected to a DC feeding circuit and still further has a load control means for controlling a load connected to the auxiliary power supply apparatus. The load control means receives, from the voltage-variable, frequency-variable inverter, an inverter status signal representative of an operating status thereof and controls the load in accordance with the inverter status signal. Moreover, the electric car control apparatus has a detecting means for detecting DC feeding information representative of a DC feeding status of the DC feeding circuit. The load control means controls the load in accordance with the DC feeding information.</p> |
