Abstract
An electric circuit in which a first switching element and a first diode element are connected in antiparallel to form an upper arm and a second semiconductor element and a second diode element are connected in antiparallel to form a lower arm, and the upper arm and the lower arm are connected in series. A gate current path in one of the upper and lower arms and a reverse recovery path in the other one of the upper and lower arms are disposed close enough and extend at least partially in parallel to each other, so as to generate mutual inductance by the reverse recovery current flowing through the reverse recovery path and the gate current flowing through the gate current path.
