Abstract:
In a drive circuit, a rate adjuster adjusts a charging speed of a MOSFET to be faster than the charging speed of an IGBT when a drive state changer changes the first switching element from the off state to the on state first, and changes the second switching element from the off state to the on state next. The rate adjuster also adjusts a discharging speed of the MOSFET to be faster than the discharging speed of the IGBT when the drive state changer changes the MOSFET from the on state to the off state first, and changes the IGBT from the on state to the off state next.
