分析了电容基脉冲电源工作放电的电路特征和续流开关导通时电路的过渡过程,根据二阶系统特性,从机理上阐明了工作放电时续流支路冲击电流形成的原因,并通过模拟实验验证了冲击电流的成因。提出了抑制硅堆续流支路冲击电流的方法,采用缓冲电阻增大二阶系统的阻尼比,能有效抑制电流)中击,防止硅堆损坏,实验表明提出的保护方案行之有效。 Based on the characteristics of the second-order system, the reasons for the formation of impulse current in the free-wheeling branch during discharge are elucidated. The simulation results show that the discharge current of the free- The experiment verifies the cause of inrush current. The method to restrain the impulse current of freewheeling branch of silicon stack is proposed. The damping resistance increases the damping ratio of the second-order system, which can effectively curb the current blow and prevent the damage of silicon piles. Experiments show that the proposed protection scheme is effective.
