Abstract

A small generator of high-power high voltage nanosecond pulses with a 12 V power source is considered. At a load of 75 Ω, it provides the generation of pulses with an amplitude of ~17 kV, a front of ~4 ns, and an energy of ~15 mJ. The maximum pulse repetition rate is 15 kHz. The generator contains an inductive energy storage device and a capacitive storage device with an operating voltage of 1 kV. The formation of high voltage pulses is carried out by a high voltage current chopper in the form of a block of drift diodes with a sharp recovery. The conditions for the effective operation of the diodes are provided by a block of parallel-connected IGBT transistors with an operating voltage of 1.2 kV. The possibility of using a generator for multispark ignition of the spark plug of an internal combustion engine is shown.

摘要

考虑使用具有12 V电源的小型高功率高压纳秒脉冲发生器。在75Ω的负载下，它产生的脉冲幅度为〜17 kV，前沿为〜4 ns，能量为〜15 mJ。最大脉冲重复率为15 kHz。发电机包含工作电压为1 kV的感应储能装置和电容储能装置。高压脉冲的形成是由高压电流斩波器以漂移二极管块的形式进行的，具有急剧的恢复。二极管有效工作的条件由工作电压为1.2 kV的一组并联的IGBT晶体管提供。示出了使用发电机对内燃机的火花塞进行多火花点火的可能性。
