The operation voltage of high voltage DC power supply of plasma filled high power microwave source PASOTRON is from -70kV up to -150kV, the total current is about 300A, while the modulator(current 60A, pulse width 60~120μs) is operating suspended on the HV DC. In practice, if the strike arc occurs, there is a strong potential to destroy the microwave tube, high voltage DC power supply, modulator or/and modular circuit of the system. The protection system of the power supply, therefore, plays an important role in the operation of system. The special designed HV crowbar and a simple self triggering circuit is applied, and a satisfied protection result is achieved. The experiments show that, 98% of the energy of the filtering capacitor would be bypassed by the crowbar after 150ns of the strike arc.

充等离子体高功率微波源 PASOTRON的高压直流电源工作电压为 -70 k V~-1 50 k V、电流为 30 0 A左右 ,而调制器又悬浮于此高压上工作 (电流为 60 A,脉宽 60~ 1 2 0 μs)。在工作中 ,一旦出现管子打火 ,很容易打坏管子、高压直流电源、调制器或控制柜的电路模块。因此 ,其控保系统就显得尤为重要。为此采用一种专门研制的高压撬棒 ,利用简单的自触发电路 ,达到了满意的保护效果。实验证明 ,从管子打火到撬棒管作出分流仅滞后 1 50 ns,可以分流掉滤波电容中 98%以上的储能 ,工作稳定可靠
