The energy efficiency of the non-thermal plasma process is primarily determined by the power conditioning system. Improvements can also be made by process changes such as injecting additives to the gas stream but this was not considered in this work. The problem of efficiently producing high voltage pulses suitable for the process and then coupling this energy to the plasma was the focus of this work. This work describes the developmental effort leading to the production of a short pulsed high voltage power supply. The developmental effort included the development of new components and circuitry with specifications exceeding the state of the art in commercial systems. After describing the developmental effort, a description of the applications of the system and experimental results obtained evaluating the system in several relevant applications are discussed. Results of efficiently coupling energy to a corona discharge plasma and the removal of NO{sub x} are included. The key technical results obtained in this work include: Development of a commercial prototype short pulsed high voltage power supplies for pollution control applications. Established a standardized circuit design that can be used to produce systems for a wide variety of applications. Demonstrated efficiency in coupling energy to a corona discharge nonthermal plasma reactor. > 90% removal of NO{sub x} from exhaust gas in laboratory tests. Development and evaluation of advanced switching and circuitry components that result in improved reliability, efficiency and reduced cost of the power system.
