Zusammenfassung:A switching system comprises: a switch (1041) comprising a first terminal (D1), a second terminal (S1) and a control terminal (G1), a first voltage (Vds1) being present between the first terminal (D1) and the second terminal (S1), a second voltage (Vgs1) being present between the control terminal (G1) and the second terminal (S1); a voltage limiter circuit (1281) including a first terminal (1361); and a feedback connection (CR1) between the first terminal (1361) and the control terminal (G1). The voltage limiter circuit (1281) is designed to perform feedback of the first voltage (Vds1) to the second voltage (Vgs1) in order to limit the first voltage (Vds1). Furthermore, the voltage limiter circuit (1281) is designed to convey the current (i1) at its first terminal (1361). The switching system further comprises a current blocking device (1221) designed to prevent the current (i1) delivered by the voltage limiter circuit (1281) from flowing via the feedback connection (CR1) to the control terminal (G1) of the s
