Problems solved by technology

[0009] In addition, as a method of suppressing noise, a technology using a noise removal device such as a snubber capacitor or a common core has been known for a long time, but when using a noise removal device, the noise removal device occupies the power conversion device (power control unit). The space in the unit) has the problem of increasing the size of the power conversion device

Abstract

The invention provides a power control unit, wherein miniaturization is achieved even when a noise removing device is arranged in the power control unit. The power control unit (30) comprises the components as follows: a buffer capacitor module (100) arranged at the side of the DC terminal portions (120a, 120b) of a power conversation module (40); and a common core (102) arranged at the side of the DC terminal portions (120a, 120b) of the power conversation module (40). The length of the common core (102) is less than the length of the buffer capacitor module (100), the buffer capacitor module (100) and the common core (102) are arranged in parallel with each other at the length direction, the buffer capacitor module (100) is aligned with one end of the common core (102) at the length direction, and the DC terminal portions (120a, 120b) are arranged at the other end of the common core (102) at the length direction.

Description

technical field [0001] The present invention relates to a power control unit capable of downsizing even when a noise removing device for suppressing noise is provided in the power control unit. Background technique [0002] As shown in Patent Document 1 described below, there is known a technique of shielding the whole by making the frame body metal to prevent noise from leaking from the power conversion device to the outside. [0003] 【Prior technical literature】 [0004] 【Patent Literature】 [0005] [Patent Document 1] Japanese National Publication No. 2005-516570 [0006] 【Summary of Invention】 [0007] 【Problems to be solved by the invention】 [0008] However, in recent years, a large number of electronic devices and the like that are easily affected by noise are installed in vehicles, and vehicles using large electric power such as EV vehicles and plug-in hybrid vehicles are increasing, and noise suppression needs to be suppressed more than ever. [0009] In additi...
