  • Publication number: 20220189930
    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.

  • Patent number: 10121773
    Abstract: A semiconductor apparatus reduces the effect of inductances and induced magnetic fields, and causes a large current to flow from one device to another device. Provided is a semiconductor apparatus comprising a first device of a first region; a second device of a second region; and a connection conductor that electrically connects the first device to the second device. The connection conductor includes current paths that are adjacent and have opposite directions in at least a portion thereof. The connection conductor causes current to flow from the first device to the second device, and causes current to flow in a direction from the second device toward the first device in at least a portion thereof.
