Document Type and Number:
Japanese Patent JP3097482
Kind Code:
B2
Abstract:
PURPOSE: To reduce the energy loss due to the self-discharge of a capacitor for supplying power to a motor generator(M/G) in a retarder in which the motor generator(M/G) is connected to an engine output shaft. CONSTITUTION: A motor generator(M/G) 2 such as an induction motor is coupled to the output shaft of an engine 1, a power capacitor 4 of a high voltage (200V or more) of a power source is electrically connected through an inverter 3 to the M/G 2, and the inverter 3 is controlled by an electronic control unit ECU 7. An auxiliary unit battery 6 and the capacitor 4 are connected by a bidirectional DC-DC converter 5 to supply power from the capacitor 4 to the battery 6 or vice versa. When the engine stops, electric energy from the capacitor 4 is transferred to the battery 6 to reduce the loss of the energy.
