Abstract

Abstract

The plasma opening switch(POS) is a critical element in inductive energy storage systems. In this paper the erosion model is introduced to analyze the foundational principle of the POS and diode system on Qiangguang I generator. The simulation waveforms of the total generator current and the diode beam current are obtained by using the erosion model and compared with experimental waveforms. The calculation results show that the POS is not completely magnetic insulated while about 60% of the total current still flow through the POS. However, about 4.5 MV diode voltage is obtained because of the rapid change rate of current.
