A drive device performs switching of at least one switch configuring an electrical power converter. The drive device includes a control section that generates a drive signal for the switch and transmits the drive signal, and at least one drive circuit that receives the transmitted drive signal. The control section generates speed adjustment information for adjusting a switching speed of the switch and transmits the speed adjustment information to the drive circuit. The drive circuit includes a speed calculation section that receives the transmitted speed adjustment information and calculates command switching speed information of the switch based on the received speed adjustment information, and a drive section that performs switching of the switch based on the received drive signal and the calculated command switching speed information.
