发明名称	Drive-Control Apparatus for Electric Drive Vehicle
摘要	A drive-control apparatus for an electric-drive vehicle drives and controls a vehicle driven by electric power generated from mechanical power produced by an internal combustion engine (1). In order to cool down an electric power converter (3) without increasing the engine-rotation speed during deceleration of the locomotive using electric braking; the drive-control apparatus includes a braking resistor (10) for dissipating electric power that is generated by a main rotating machine (4) and supplied through the electric power converter (3); a fan motor (7), whose pole number is changeable, supplied with alternating electric power that is generated by an auxiliary generator (6) and has a frequency proportional to a rotation speed of the internal combustion engine (1); a fan (8) for making an air flow in order to cool down the electric power converter (3), being driven by the fan motor (7); a pole-number-changing switch (9) for changing the pole number of the fan motor (7); and a controlling unit for controlling the internal combustion engine (1), the electric power converter (3), the braking resistor (10), and the pole-number-changing switch (9).
