A power converter (100) for a vehicle according to an embodiment includes four semiconductor element modules (13a, 13b, 13c, and 13d) that each include silicon carbide (SiC) for a switching element (101) that performs switching operation and a freewheeling diode (102) that passes a freewheeling current and include circuits for three phases, each of the circuits being related to single-phase AC output and having arms each of which connects the freewheeling diode anti-parallel to the switching element, the arms being connected in series as circuits that perform three-phase AC output for driving one permanent magnet synchronous motor and a cooling unit (1) that cools the four semiconductor element modules.
