COLD CATHODE THYRATRON CONTROL DEVICE Russian patent published in 2017 - IPC H02M1/04 H03K3/543 H01J17/38 

FIELD: electricity.

SUBSTANCE: control device includes a step-up voltage pulse transformer (9), a capacitive energy storage (5), a pulse hydrogen thyratron (15) and a trigger generation unit containing a thyristor (8) included in the transformer primary circuit (9), a shunting capacitor (18) connected to the thyristor control electrode (8), a saturation throttle (6) and the second shunting capacitor (7), which reduces the stress rate across the thyristor (8). To delay the voltage supply to the grid of the pulse hydrogen thyratron (15) relative to the trigger of the thyristor (8) to the thyristor (8) control electrode and a clock pulse generator (19) is connected to the grid of the hydrogen thyratron (15). A capacitive energy storage (5) can be connected to an alternating voltage circuit via a step-up voltage pulse transformer (9) and a mains single-ended rectifier (1).

EFFECT: possibility of using the device in generator schemes, both with pulse charging of the storage capacitor, and with DC charging, increasing reliability due to reducing the number of elements and operating efficiency, providing parallel operation of two thyratrons of the TDI series.
