Abstract
A driving device of an IGBT includes a high potential side switch device group having a plurality of switch devices and, one end of each switch device being connected to a high potential side; a low potential side switch device group having a plurality of switch devices and, one end of each switch device being connected to a low potential side; an drive type selective input terminal to which a drive type selection signal corresponding to drive type of the IGBT connected to the driving device is inputted; a direct drive type control unit and an indirect drive type control unit generating a control signal controlling complementarily the high potential side switch device group and the low potential side switch device group corresponding to the drive type of the IGBT; and a selector selecting the control signal controlling the high potential side switch device group and the low potential side switch device group corresponding to an inputted drive type selection signal.
