  • POWER CONVERTER
    Publication number: 20120235162
    Abstract: This power converter includes a power-conversion semiconductor element, an electrode conductor having a substantially flat upper end surface, and a sealant. The sealant allows the substantially flat upper end surface of the electrode conductor to be exposed at an upper surface of the sealant, and provides electrical connection with an external device at the upper end surface of the exposed electrode conductor.
