摘要

A terminal electrode of the discharge capacitor is coupled to the switch electrode which changes its electric potential on disconnection of the switch current in relation to the system determining the blocking voltage of the switch. The second capacitor electrode is connected to the switching point with blocking voltage via one diode. This point of the circuitry which has a voltage approximating the blocking voltage in relation to the main electrode parameters. The remaining second terminal electrode of the capacitor is connected to a point of the circuitry, via the other diode and the choke, series connected to the diode. The polarisation of the first diode is so selected as to block the current flow between specified circuit points, even when the second diode is short circuited.
