Design of trigger device for repetitive pulsed power system

According to the trigger method of high-power switch device hydrogen thyratron used in the repetitive pulsed power system， a trigger device was designed for hydrogen thyratron VE4147， which can output -150 V DC bias， and pulses with voltage 2 000 V， current 10 A， width 800 ns and repetition-rate up to 10 kHz. The design takes into account interference protection， low power consumption， thermal management and so on， to make sure that such trigger device can work uninterruptedly at the repetition-rate of 10 kHz. So far the trigger device has been used in sorts of repetitive pulsed power systems， such as 100 kV/2 kHz high-voltage pulsed power supply， 70 kV/10 kHz hydrogen thyratron aging platform， and 150 kV/1 kHz corona plasma generator of adjustable pulse width.
