According to one embodiment, a power converter for a vehicle includes four semiconductor element modules and a cooling unit. The four semiconductor element modules each include a switching element and a freewheeling diode and form circuits for three phases as circuits that perform three-phase AC output for driving one permanent magnet synchronous motor, the switching element using silicon carbide (SiC) and performing switching operation, the freewheeling diode using silicon carbide (SiC) and passing a freewheeling current, 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. The cooling unit cools the four semiconductor element modules.
