Abstract
An electric power conversion device including: a voltage conversion circuit that converts a DC voltage; an inverter circuit that converts the DC voltage into an AC voltage; a negative electrode bus bar commonly connected to the voltage conversion circuit and the inverter circuit; a first positive electrode bus bar connected to the voltage conversion circuit; a second positive electrode bus bar connected d to the inverter circuit; a housing that accommodates the voltage conversion circuit and the inverter circuit; and a first heat dissipation member provided in the housing, in which the first positive electrode bus bar, the second positive electrode bus bar, and the negative electrode bus bar are stacked and electrically insulated from each other, the first positive electrode bus bar and the second positive electrode bus bar are opposite to the first heat dissipation member across an insulating member, and at least one of the first positive electrode bus bar and the second positive electrode bus bar is in thermal contact with the first heat dissipation member via the insulating member and the first heat conductive member.
