【Abstract】 Pulses with fast rise front and short duration are requird for rcmoval of SO2 / NOx from flue gas by means of corona discharge. This paper discusscs the development and analysis of noval pulse generator for this application. The voltage pulses had been achieved with adjustable crest value and dc bias voltage and with a rise time of less than 20ns and pulse width of less than 100ns. Furthermore, the pulse energy transfer cfficiency of 95% and the overall power efficiency of more than 70% have been achieved, respectively.更多还原
