Title:
POWER CONVERSION DEVICE
Document Type and Number:
Japanese Patent JP2023177397
Kind Code:
A
Abstract:
To obtain a power conversion device capable of improving a heat radiation property of a bus bar while suppressing increase in wiring inductance between a capacitor element and a power module.SOLUTION: A power conversion device comprises: a power module part that has a plurality of power terminals; and a capacitor module that has a capacitor element, a capacitor case, and a capacitor bus bar. The capacitor bus bar has a flat plate part exposed to the outside, a plurality of power terminal connection parts, a power supply connection part, and a plurality of element connection parts. A position range of the element connection parts that is a position range in a first direction between two element connection parts arranged at both ends, and a position range of the power terminal connection parts that is a position range in the first direction between two power terminal connection parts arranged at both ends, are inside a position range in the first direction where the flat plate part is arranged. A length of the position range of the element connection parts and that of the position range of the power terminal connection parts are equivalent to each other. A center position of the position range of the element connection parts and that of the position range of the power terminal connection parts are equivalent to each other.SELECTED DRAWING: Figure 2
