Problems solved by technology

Therefore, when the leakage flux of the reactor is shielded by the case or other internal components, the leakage flux is converted into heat due to the eddy current generated in the conductive member when the leakage flux passes through the conductive member. To ensure the desired leakage inductance, it may be necessary to increase the size of the reactor

Abstract

The present invention provides an electric power control apparatus and a drive unit capable of ensuring inductance required for a desired boost operation. The electric power control apparatus includesa controller that controls transfer of electric power between a motor and a power storage device; and a case that accommodates the controller. The controller includes a magnetically coupled reactor.At least part of the case around the reactor includes a non-conductive wall portion formed of a non-conductive material.

Description

technical field [0001] The invention relates to a power control device and a drive unit. Background technique [0002] Conventionally, there is known a power conversion device including a resin-embedded semiconductor element, a capacitor, and a reactor in a housing in order to improve vibration damping performance (for example, refer to Japanese Patent Laid-Open No. 2009-232564 ). [0003] In addition, conventionally, a converter (power conversion device) using a reactor including magnetically coupled coils is known (for example, refer to JP-A-2014-127637). [0004] For example, a magnetically coupled reactor included in a booster circuit etc. actively utilizes inductance caused by leakage magnetic flux generated three-dimensionally to perform a boosting operation. [0005] On the other hand, in a power conversion device, electromagnetic shielding is generally performed by a conductive member (a housing made of aluminum, etc.) arranged to shield a high-frequency magnetic fi...
