Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/031408
Kind Code:
A1
Abstract:
Provided is a power conversion device in which cooling efficiencies of a capacitor and a current sensor can be improved and the whole length of the device can be reduced in the projection direction of power terminals. The power conversion device is provided with: a laminate (10) obtained by laminating semiconductor modules (2) and cooling pipes (11); a capacitor (3); and a current sensor (4). The semiconductor modules (2) include upper-arm semiconductor modules (2U) and lower-arm semiconductor modules (2L). The upper-arm semiconductor modules (2U) and the lower-arm semiconductor modules (2L) are alternately laminated in the lamination direction (X direction) of the laminate (10). The capacitor (3) is disposed on one side of the laminate (10) in the orthogonal direction (Y direction) orthogonal to both the X direction and the projection direction (Z direction) of power terminals (22) in the semiconductor modules (2), and the current sensor (4) is disposed on the other side thereof.
