Abstract:
An electric power converter ( 100 ) which is provided with a switching element ( 101 ) and a rectifying element ( 102 ) that is connected in series to the switching element ( 101 ). This electric power converter ( 100 ) has a configuration wherein an external electrical load ( 103 ) is connected to the connection point of the switching element ( 101 ) and the rectifying element ( 102 ). The switching element ( 101 ) is composed of an insulating gate type semiconductor element that has a first gate terminal ( 105 ) and a second gate terminal ( 106 ). The rectifying element ( 102 ) is composed of a diode that has a Schottky junction which uses silicon carbide as a semiconductor base. Different driving signals are applied to the first gate terminal ( 105 ) and the second gate terminal ( 106 ), respectively.

Claim (Index 2):
The power conversion device according to  claim 1 , wherein the insulated gate semiconductor element comprises:\n a first-conductive-type first semiconductor layer; a second-conductive-type second semiconductor layer provided on a first surface of the first semiconductor layer; a plurality of trenches penetrating the second semiconductor layer from a surface of the second semiconductor layer not contacting the first semiconductor layer and reaching the first semiconductor layer; a plurality of gate electrodes configured to include a conductor provided in each of the plurality of trenches and an insulating film provided around the conductor; a first-conductive-type third semiconductor layer provided on a surface of the second semiconductor layer not contacting the first semiconductor layer to be adjacent to the gate electrodes; a second-conductive-type fourth semiconductor layer provided on a second surface of the first semiconductor layer; an emitter electrode provided on a surface of the second semiconductor layer not contacting the first semiconductor layer and a surface of the third semiconductor layer; and a collector electrode provided on a surface of the fourth semiconductor layer not contacting the first semiconductor layer, wherein the plurality of gate electrodes comprises\n a first gate electrode connected to the first gate terminal; and \n a second gate electrode connected to the second gate terminal.
