ABSTRACT:
The device consists of a series network of a rectifier and a choke connected in parallel with a gas-discharge vessel and a capacitor. Between an intermediate tap of the primary of the saturating transformer and the positive terminal of the recitifer a thyristor is connected so that its cathode is connected with the intermediate tap. The control circuit of the thyristor consist of connected with each other secondary of the saturating transformer, unit for control pulse shaping, whose input is connected with the output of a voltage sensor mounted across the gas-discharge vessel. Between the intermediate tap of the primary of the saturating transformer and the positive terminal of the rectifier a series circuit of a diode and a second choke is connected so that the anode of the diode is connected with the intermediate tap.
