Design and application of high-voltage nanosecond switches based on PCSS triggered thyristor surge suppressor arrays
摘要
Abstract
The solid-state high-voltage pulse switch with high index,compact structure and good stability is of great significance to the progress of pulse power technology.This paper proposes a high-voltage nanosecond switching technology route based on Photoconductive Semiconductor Switches(PCSS)and thyristor surge suppressor(TSS)arrays,and a new type of high voltage switching module(PCSS triggering thyristor surge suppressors module,PTTSSM)is developed by using PCSS,which is convenient for realizing the high-voltage isolation,as the triggering unit of TSS arrays.The 20 kV PTTSSM has a peak output current of 23.7 A,a pulse width of 122.1 ns,a rise time and a fall time of 55.9 ns and 128.3 ns,respectively,and a size of 60 mm×60 mm×40 mm.The 100 kV PTTSSM has an adjustable peak output voltage of 60-100 kV,a maximum peak output current of 356 A,a pulse width of 1.308µs,rise time and fall time of 160.4 ns and 2.454µs,respectively,and its size is 150 mm×100 mm×50 mm.All of them can work stably for a long time.Pulse power supply based on a new solid-state switching module successfully generates a large number of stable low-temperature plasmas in organic wastewater treatment experiments,verifying the feasibility and effectiveness of the switching module-driven plasma generation.关键词
