Abstract
A semiconductor switching module includes an insulated gate bipolar transistor and a unipolar switching device. The insulated gate bipolar transistor includes a first transistor cell and a supplemental cell, wherein the first transistor cell includes a first gate and a first source and wherein the supplemental cell includes a second gate and a supplemental electrode. The unipolar switching device is based on a wide bandgap material and includes a third gate and a third source. The third gate and the second gate are electrically connected with each other and are disconnected from the first gate. The first source, the supplemental cell and the third source are electrically connected with each other.
