摘要: 根据重复频率脉冲功率系统中大功率开关器件氢闸流管的触发原理，针对选用的氢闸流管VE4147的触发要求，设计了直流偏压-150 V、空载电压2 000 V、脉冲电流10 A、脉冲宽度800 ns、重复频率10 kHz的触发器。设计中着重从增强抗干扰能力、降低功耗、改善散热等方面进行考虑，保证触发器以10 kHz的重复频率持续工作，已经应用于100 kV/2 kHz高压脉冲电源、70 kV/10 kHz氢闸流管老练平台、150 kV/1 kHz可调脉宽电晕等离子体驱动源等多个重复频率脉冲功率系统中。Abstract: 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.
