Characteristics of a fast rise time power supply for a pulsed plasma reactor

Organic contaminants removal by the technique of pulsed high-voltage discharge in water

“…At present, the power supply used for wastewater treatment was the same as that used for air pollution control and had two sorts. The one used pulsed transformer to generate pulsed voltage [19,20], and the other used rotating spark gap or gastriode to form the voltage [21,22].…”

Nonthermal Plasma Processing for Controlling Volatile Organic Compounds

“…The use of nonthermal plasma technologies to decompose various VOCs has been investigated using pulsed corona [Futamura et al, 1995;Chang et al, 1991Chang et al, , 1995Yamamoto el al., 1992Yamamoto el al., , 1993Yamamoto el al., , 1995Hsiao et al, 1995;Abolentsev et al, 1993;Mizuno et al, 1993;Lawless et al, 1993;Masuda el al., 1993;Hosokawa, 1995;Kito, 1995], packed-bed Nunez et al, 1993], silent corona [Coogan el al., 1993;Rosocha et al, 1993Rosocha et al, , 1994Evans et al, 1993], and surface discharge reactors [Oda et al, 1992[Oda et al, , 1994Masuda et al, 1988. Decomposition of VOCs is affected by the type of reactors, operating conditions, background gases.…”

Modified multistage semiconductor-Fitch generator topology with magnetic compression

“…Equation 4 summarizes the advantage of the topology introduced, a fact of tripling the supply voltage on a single voltage stage.…”

“…Modern plasma technology systems often require high voltage, high current, short duration pulse power supplies [1,2,3,4]. Although fast development of modern power switches (most of all thyristors and LTTs) results in high blocking voltage ratings, costs and rise and fall times are often hard to adopt in pulsed power systems, most of all considering sources with short rising and falling edge demands.…”
