A pulsed-power generator using inductive adder technology is proposed for the case of a discharge gap. The merit of this generator is to merge the pulsed-voltage and pulsed-current adders via the dual secondary windings with special circuit. For the nonlinear impedance in any discharge gap, the standalone voltage-pulse and current-pulse can be outputted successively by this generator. The proposed generator is especially useful for the common resolution of implementing pulse discharge at less cost. As an application example, a compact trigger prototype was developed to compatibly use in the gas-insulated and vacuum switches. Experiments achieved good results that the triggered switches showed stable performance and long life. If the basic circuit of this proposed generator is regarded as a pulsed-generating unit, a certain number of such units connected in parallel can be expected to form a general device with generating greater breakdown-voltage and sustained-current pulses for discharge gaps.
针对放电间隙的情况，提出了一种采用感应叠加器技术的脉冲功率发生器。该发生器的优点是通过具有特殊电路的双二次绕组将脉冲电压叠加器和脉冲电流叠加器合并。对于任何放电间隙中的非线性阻抗，该发生器都能相继输出独立的电压脉冲和电流脉冲。所提出的发生器对于以较低成本实现脉冲放电的常见解决方案特别有用。作为一个应用示例，开发了一种紧凑的触发器原型，以兼容用于气体绝缘开关和真空开关。实验取得了良好的结果，触发开关表现出稳定的性能和长寿命。如果将所提出的发生器的基本电路视为一个脉冲发生单元，那么可以预期将一定数量的这种单元并联连接，以形成一个能够为放电间隙产生更高击穿电压和持续电流脉冲的通用装置。
