SWITCHING DEVICE FOR A SWITCHING OPERATION AT A HIGH WORKING VOLTAGE

摘要

A switching device for switching at a high operating voltage includes an LV switching element and a first HV switching element that are connected together in a cascode circuit. Furthermore, at least a second HV switching element is connected in series with the first HV switching element. A first protection element is connected between the HV grid terminals of the first and second HV switching elements, respectively.
