ELECTRIC POWER CONVERTER FOR ELECTROMOTIVE VEHICLE

摘要

An electric power converter (10) is divided into a main casing (10a) and an auxiliary casing (10b). The main casing (10a) contains a high-voltage circuit (28, 29) through which electric power for driving a motor (83) flows. The auxiliary casing (10b) contains a control circuit (19) configured to control the high-voltage circuit. The auxiliary casing (10b) is connected to the main casing (10a) by a cable (23). The main casing (10a) and the auxiliary casing (10b) are accommodated in a front compartment (2) of a vehicle together with a motor case (3) that accommodates the motor. The main casing (10a) is fixedly mounted on the motor case (3). The auxiliary casing (10b) is arranged so as to be adjacent to the main casing (10a) and is fixed to a body of the vehicle.

主权项

1. An electric power converter that converts electric power of a battery to supply the converted electric power to a drive motor, the electric power converter characterized by comprising:
a main casing containing a high-voltage circuit through which electric power for driving the motor flows, the main casing being fixedly mounted on a motor case that accommodates the motor, the main casing being accommodated in a front compartment of a vehicle; and an auxiliary casing connected to the main casing by a cable, the auxiliary casing containing a low-voltage circuit that operates at a voltage lower than a voltage of the battery and that is configured to control the high-voltage circuit, the auxiliary casing being arranged so as to be adjacent to the main casing, the auxiliary casing being fixed to a body of the vehicle, the auxiliary casing being accommodated in the front compartment of the vehicle.
