Title:
POWER MODULE CAPACITOR AND POWER CONVERSION DEVICE PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2024/004267
Kind Code:
A1
Abstract:
A capacitor according to the present disclosure is provided with: a plurality of capacitor elements arranged side by side in a housing; positive electrode conductors that each connect the positive electrode of each capacitor element with the positive electrode of a power module; negative electrode conductors that each connect the negative electrode of each capacitor element with the negative electrode of the power module while holding the plurality of capacitor elements between the positive and negative electrode conductors; insulation portions that are provided in the housing to fill spaces between the inner surfaces of the housing, the plurality of capacitor elements, the positive electrode conductors, and the negative electrode conductors and thereby insulate the same from each other; and a conductive plate that is formed from a material with higher heat conductivity than the insulation portions and that is disposed, with the intermediation of the insulation portions, between a positive electrode conductor current path extending from each capacitor element to the power module and a negative electrode conductor current path extending from each capacitor element to the power module in the housing such that the insulation portions are interposed between the positive and negative electrode conductors.
