Title:
POWER CONVERSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/032060
Kind Code:
A1
Abstract:
Provided is a power conversion device comprising: a voltage conversion circuit which converts DC voltage; an inverter circuit which converts the DC voltage to AC voltage; a negative electrode bus bar which is connected in common to the voltage conversion circuit and the inverter circuit; a first positive electrode bus bar which is connected to the voltage conversion circuit; a second positive electrode bus bar which is connected to the inverter circuit; a housing in which the voltage conversion circuit and the inverter circuit are housed; and a first heat dissipation member which is provided in the housing, wherein the first positive electrode bus bar, the second positive electrode bus bar, and the negative electrode bus bar are layered and provided so as to be electrically insulated from each other, the first positive electrode bus bar and the second positive electrode bus bar face the first heat dissipation member with an insulation member therebetween, and the first positive electrode bus bar and/or the second positive electrode bus bar thermally contacts the first heat dissipation member via the insulation member and a first heat conducting member.
