Zusammenfassung:	Provided are a power conversion device and the like having a simple configuration and a low loss. An inverter (100) is provided with: a switching element drive circuit (20) for outputting drive signals to switching elements (Qa, Qb); reverse voltage application circuits (30a, 30b) for applying reverse voltages to the parasitic diodes (Da, Db) or free-wheeling diodes of the switching elements (Qa, Qb); and multivibrators (40a, 40b) for generating reverse voltage application signals to the reverse voltage application circuits (30a, 30b) using the drive signals input thereto from the switching element drive circuit (20).
