  • Patent number: 11949338
    Abstract: A power converter includes a positive busbar electrically connected to a positive terminal and the first capacitor electrode, and includes a negative busbar electrically connected to a negative terminal and the second capacitor electrode. The power converter includes output busbars each electrically connected to a given output terminal among multiple output terminals, a given high-side switching element among a plurality of high-side switching elements, and a given low-side switching element among a plurality of low-side switching elements. The power converter includes a cooler that cools the high-side switching elements and the low-side switching elements. The power converter includes a housing that accommodates a supply tube and a discharge tube. The positive terminal, the negative terminal, the output terminals, the inlet port, and the outlet port are exposed on the housing. The inlet port, the outlet port, the supply tube, and the discharge tube are separate members from the housing.
