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-150V、空载电压2 000V、脉冲电流10A、脉冲宽度800ns、重复频率10kHz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10kHz的重复频率持续工作,已经应用于100kV/2kHz高压脉冲电源、70kV/10kHz氢闸流管老练平台、150kV/1kHz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。
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.
