Abstract
The present disclosure relates to a semiconductor switch leg S for a Power Electronic (PE) converter (). The switch leg comprises a plurality of parallel connected semiconductor devices Sa-d. Each semiconductor device is connected with a positive conductor a-d+ connecting the semiconductor device to a positive terminal of an energy storing device () of the converter, and a negative conductor a-d-connecting the semiconductor device to a negative terminal of the energy storing device () of the converter, the semiconductor device together with the positive conductor and the negative conductor forming a current path across the energy storing device. The semiconductor switch leg comprises a plurality of magnetic coupling devices-, each magnetic coupling device being arranged between the two current paths of respective two neighbouring semiconductor devices of the plurality of semiconductor devices such that the current path of one of the two semiconductor devices and the current path of the other of the two semiconductor devices pass via the magnetic coupling device, and such that each current path passes via two of said plurality of magnetic coupling devices.
