We designed a fast capacitive high voltage probe for a Marx generator. Since the capacitive probe works on differential mode, we designed also a fast passive integrator to integrate the signals. We tested the probe's performance by using a simple pulse generator to simulate the Marx generator signals. We calibrated the probe using a calibrated water load which act as a resistive voltage divider. We...
We designed a Marx generator for repetitive applications. The Marx generator has 25 stages. Each stage was constructed 4 door knob ceramic capacitors and a ball spark gap switch. We used the inductor charging method for higher repetitive operation. The designed maximum output voltage of the Marx generator is 1 MV at open circuit condition. The overall size of the Marx generator is 150 cm in length...
The structure of an air-core cylindrical high voltage pulse transformer is relatively simple, but considerable attention is needed to prevent breakdown between transformer windings. Since the thickness of the spiral windings is on the order of sub-millimeter, field enhancement at the edges of the windings is very high. Therefore, it is important to have proper electrical insulations to prevent breakdown...
A multi-gap multi-channel (MGMC) switch of 500 kV has been developed at Pohang Accelerator Laboratory (PAL). It consists of ten of gaps to increase self-discharge voltage by filling up the gas. A structure of a multi-gap switch can increase its inductances. Thus, in order to solve those problems its structure made by multi-channels had been designed to decrease the inductance effects. The fabricated...
