Abstract: A drive device (15) that drives a power conversion device (9) having a switching element (3) that is formed by a wide band semiconductor comprises: a PWM signal output section (11) that generates a drive signal that performs PWM drive of the switching element (3); an ON speed reduction section (13) that reduces the rate of change of the drive signal when the switching element (3) is changed from OFF to ON; and an OFF speed improvement section (14) that recovers charge from the switching element (3) at high speed and with load recovery capability that is higher than during change from OFF to ON when the switching element (3) is changed from ON to OFF.
