Abstract:
A power converter for converting DC power to AC power by switching operation of a switching element includes: a bridge circuit configured by at least two series circuits using, as power input terminals, terminals on both sides of two switching elements connected to each other in series and using, as a power output terminal, a connection point of the two switching elements are connected in parallel via the power output terminal; a gate drive circuit for outputting a driving signal which controls to turn on/off the switching elements; and signal lines using a driving signal output terminal in the gate drive circuit as a starting point of wiring, individually hard-wired to each of the switching elements in each of series circuits to which the same driving signal is supplied from the driving signal output terminal, and having inductances which are configured equal to each other.
