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 11):
The power conversion device according to  claim 10 , wherein the third semiconductor layer comprises:\n a first layer of the third semiconductor layer adjacent to the first gate electrode; and a second layer of the third semiconductor layer adjacent to the second gate electrode, wherein a direction orthogonal to a depth direction of the trench and a width direction of the trench is set as a depth direction, wherein the third semiconductor layer is repeatedly provided in the depth direction, and wherein a ratio a 1 /b 1  of a length a 1  of the depth direction of the first layer of the third semiconductor layer and a length b 1  of a repetition unit of the depth direction of the second semiconductor layer including the first layer of the third semiconductor layer is different from a ratio a 2 /b 2  of a length a 2  of the depth direction of the second layer of the third semiconductor layer and a length b 2  of a repetition unit of the depth direction of the second semiconductor layer including the second layer of the third semiconductor layer.
