According to one embodiment, a power converter for a railroad vehicle includes a semiconductor device, a first heat receiving member, a reactor and a resistor, a second heat receiving member, a coolant circulation loop, and a heat exchanger. The semiconductor device constitutes a main circuit unit that carries out power conversion. The semiconductor device is attached to the first heat receiving member. The reactor and the resistor constitute an auxiliary circuit unit that carries out power conversion. The reactor and the resistor are attached to the second heat receiving member. The coolant circulation loop causes a coolant to flow through the first heat receiving member and the second heat receiving member. The heat exchanger allows heat exchange with respect to the coolant to occur.
