LC generator is widely applied in the field of high voltage generation technology. A compact and all solid-state LC high voltage generator based on saturable pulse transformer is proposed in this paper. First, working principle of the generator is presented. Theoretical analysis and circuit simulation are used to verify the design of the generator. Experimental studies of the proposed LC generator with two-stage main energy storage capacitors are carried out. And the results show that the proposed LC generator operates as expected. When the isolation inductance is 27 μH, the output voltage is 1.9 times larger than the charging voltage on single capacitor. The multiplication of voltages is achieved. On the condition that the primary energy storage capacitor is charged to 857 V, the output voltage of the generator can reach to 59.5 kV. The step-up ratio is nearly 69. When self breakdown gas gap switch is used as main switch, the rise time of the voltage pulse on load resistor is 8.7 ns. It means that the series-wound inductance in the discharging circuit is very small in this system. This generator can be employed in two different applications.
LC发生器在高压产生技术领域有着广泛应用。本文提出了一种基于可饱和脉冲变压器的紧凑型全固态LC高压发生器。首先，介绍了该发生器的工作原理。运用理论分析和电路仿真来验证发生器的设计。对所提出的具有两级主储能电容器的LC发生器进行了实验研究。结果表明，所提出的LC发生器运行符合预期。当隔离电感为27 μH时，输出电压比单个电容器上的充电电压大1.9倍。实现了电压倍增。在初级储能电容器充电至857 V的条件下，发生器的输出电压可达到59.5 kV。升压比接近69。当使用自击穿气隙开关作为主开关时，负载电阻上电压脉冲的上升时间为8.7 ns。这意味着该系统中放电电路的串联电感非常小。该发生器可用于两种不同的应用。
