| 摘 要： | 为研究气体间隙的放电特性，设计了输出幅度在30～100 kV、重复频率1～5 kHz可调的高压脉冲电源。利用谐振充电的原理，将10 kV的初级电源的能量转移到中储电容，中储电容的电压升高到至少18 kV。在光触发信号的作用下,氢闸流管导通，中储电容上的能量通过脉冲变压器放电，在脉冲变压器的副边得到最大幅度为100 kV的负脉冲，其脉宽大于200 ns,前沿时间小于90 ns。整个装置在不加散热系统的情况下,可连续工作1 min以上。

| Abstract: | To study the characteristics of gaseous discharge in spark gap, a high-voltage pulsed power supply has been designed, whose output voltage amplitude varies between 30～100 kV and repetition-rate varies from 1 Hz to 5 kHz. Adopting the principle of resonant charging, the power supply transferrs energy from the primary source of 10 kV DC to the secondary energy storage capacitor that is charged at least to 18 kV. The hydrogen thyratron conducts under the action of optical trigger signal. Then the current flows through the pulse transformer, and voltage is raises from 18 kV to the peak of 100 kV. The output pulse is a negative voltage one with an pulse width of at least 200ns. and fall time less than 90 ns. The device can continuously run for no less than 1 min without additional cooling system. |
