ELECTRONIC GAS DISCHARGE TUBE STARTER HAVING A SEMICONDUCTOR SWITCH ELEMENT CONTROLLED BY A CAPACITIVE VOLTAGE DIVIDER

摘要

An electronic gas discharge tube starter comprises a semiconductor switch element with a separate control signal terminal connected through a semiconductor switch diode to the node between two capacitors included in a circuit connected in parallel with the switch element. According to the invention, the capacitors can exclusively be charged through a diode. It is thus ensured that after a predetermined time the voltage generated in the node has decreased to the extent that the switch diode is no longer capable of igniting the tube.
