Abstract (en)
A DC power switching unit comprises a first terminal and a second terminal (24, 25), a sub-unit comprising a current limiter (L, L1, L2) and a diode (D1, D2) and a semiconductor device (Q1, Q2). The sub-unit is connected to a first side (31) of the semiconductor device. The power switching unit further comprises a snubber circuit (30) connected to a second side (32) of the semiconductor device. The power switching unit comprises two symmetrical sub-units, each sub-unit being connected on one side to one of the first and second power switching unit terminals and on the other side to the semiconductor device (Q1, Q2).
