A high-reliability IGBT drive device in which the high- and low-voltage side IGBTs are complementarily ON/OFF controlled before and after dead time. A reset pulse that turns OFF the high-voltage side IGBT is generated during the dead time as described in the following example. The reset pulse is generated immediately before an ON instruction for the low-voltage side IGBT, so that a period that begins immediately before the ON instruction for the low-voltage side IGBT and overlaps with the ON instruction, continuously during the dead time, continuously during dead time immediately before the low-voltage side IGBT turns ON, or in such a manner as to invalidate the ON instruction for the low-voltage side IGBT when an ON state of the high-voltage side IGBT is observed.
