Abstract

See full text

Provided is a power converter 3 that directly converts polyphase AC power to AC power. A converter circuit has a plurality of first switching elements 311, 313 and 315 that are connected to each phase R, S or T of the polyphase AC power to enable switching for turning on current-carrying bidirectionally, and a plurality of second switching elements 312, 314 and 316 that are connected to each phase to enable switching for turning on current-carrying bidirectionally. The converter circuit comprises input lines R, S and T connected to each input terminal, and output lines P and N connected to each output terminal. Parts of wiring 347 and 348 of protection circuits 32 are located between output lines P and N. The wiring distance between each protection circuit 32 and the corresponding switching element can be shortened.
