Abstract

An inverter control device to drive a motor includes a power module that supplies a driving current to the motor. The inverter control device further includes a power module board that outputs a driving signal to the power module, a control board that outputs a control signal to the power module board, and a smoothing capacitor. The power module, the power module board, the capacitor, and the control board are sequentially stacked and accommodated in a single casing made of a metal material, the power module being a bottommost layer. An input terminal of a power supply current is located on one side surface of the casing and an output terminal of a driving current of the motor is located on another side surface of the casing orthogonal to the one side surface, and the output terminal and abus bar connected to the power module are directly connected to each other in a same plane.

Description

technical field [0001] The present disclosure relates to the configuration of an inverter control device as a power conversion device for a vehicle. Background technique [0002] As environment-friendly vehicles in recent years, electric vehicles, hybrid vehicles, and the like that use electric motors as a drive source have begun to spread. These electric vehicles and the like are equipped with an inverter device (power conversion device) that converts DC power from the battery into AC power supplied to the drive motor, and affects the motor rotation speed and drive torque. Acceleration and deceleration of the vehicle are performed under control. [0003] Such an inverter device requires not only high performance and high reliability but also miniaturization with emphasis on vehicle mountability. In particular, in the case of a vehicle-mounted inverter device, there is a strong demand for a smaller size than conventional ones due to restrictions on the interior space of th...
