Abstract:
Insulator surface flashover is one of the bottlenecks restricting the development of pulsed power technology. To obtain a deeper understanding of flashover mechanism, UV illumination was introduced into surface flashover process. The flashover perfor...

Abstract:
A Blumlein-PFN (BPFN) was fabricated and the factors that affect energy transfer efficiency were investigated. The BPFN is composed of ceramic capacitor, aluminum strip and GaAs-PCSS. Air-gap was selected as the BPFN pulse forming switch first, then ...
