Abstract
In the railway vehicle power conversion device, an air flow passage is formed by providing an L-shaped partition plate whose long side is in the rail direction, in the interior of a box suspended below the floor of the vehicle. On one side of this partition plate, there are included, in order of the rail direction, a high-speed circuit breaker, relay unit, interface unit and control device. On the other side of partition plate, a pair of smoothing reactors are included on the short side of L-shaped partition plate, and a semiconductor cooling unit is included on the other side of the smoothing reactors and partition. A heat-radiating part of this semiconductor unit projects at the side of air inlet port of air flow passage. Electrically driven fans are fixed within an airflow passage at the smoothing reactors.
