摘要：

In this paper, a new-type resonant charging device, which substantially decreases the rise time of loading voltage with the combination of boost action of pulse transformer and steepen action of magnetic switch, is constructed based on the saturable pulse transformer. The parameters are determined for the requirements of investigation on the initial stage of fast wire-array Z pinch by analyzing the working modes of resonant charging devices. The delay jitter in self-breakdown of a gas spark switch driven by the new resonant charging device decreases by at least 50% of delay jitter in the situation using a traditional resonant charging device. The delay jitter is 13ns with the initial charging voltage of 19kV, the electrode space of 5.5mm and the inner gas pressure of 1.01325X105Pa. The stability of self-breakdown voltage is also increased drastically under higher inner pressure in gas spark switch. The technical approach for construction of pulsed power generator using a pulse transformer with steepen action of gas spark switch is improved. The newly-constructed compact pulsed power generator can output a pulsed current in a level of pre-pulse current of wire-array Z pinch with extremely low jitter in time delay and relatively high stability in breakdown voltage. The pulsed power generator with low delay jitter can facilitate synchronous diagnosis of high temporal-spatial resolution for the initial stage of wire-array Z pinch. © 2023 Chinese Society for Electrical Engineering.
