Title: SWITCHING ELEMENT DRIVE UNIT
Abstract:
Provided is a switching element drive unit with which it is possible, even when a semiconductor switching element configured from a wide-gap semiconductor is used, to reduce the connection distance between a driver and the semiconductor switching element while maintaining insulation between the driver and a cooler. A switching element drive unit (30) provided with: a circuit board (1); a semiconductor switching element (102a) configured from a wide-bandgap semiconductor; a cooler (4); and a driver (103a), the driver (103a) being surface-mounted on a second surface (32) on the opposite side to a first surface (31), which is the surface of the circuit board (1) on the side at which the cooler (4) is disposed.
