POWER CONVERSION DEVICE AND VEHICLE EQUIPPED WITH POWER CONVERSION DEVICE

Document Type and Number:

WIPO Patent Application WO/2019/026339

Kind Code:

A1

Abstract:

In a high-density mounting small power conversion device in which a distance between a bus bar and a drive circuit board is reduced, the driving circuit board receives a blast of heat from the bus bar. Heat buildup due to self-heating of the drive circuit board is generated by mounting a capacitor on the upper side in close proximity to the drive circuit board. These factors cause a problem such as a malfunction or life reduction of the drive circuit board. To cope with this, in a cooler for cooling a 2-in-1 power module, a plurality of 2-in-1 power modules are arranged side by side in the vertical direction, which is the longitudinal direction of the 2-in-1 power modules, bus bars connected to the 2-in-1 power modules are arranged on one sides in the transverse direction of the 2-in-1 power modules, and control signal lines connected to the 2-in-1 power modules are arranged, together with a drive circuit board for sending a control signal to the control signal lines, on the opposite sides of the one sides in the transverse direction of the 2-in-1 power modules.
