The pulse-induced plasma chemical process (PPCP) is a novel means of processing with great potential in various applications including the removal of No, SO{sub 2}, HCl, and Hg vapor and other gaseous pollutants from combustion gases, the composition of new gaseous and solid substances, the production of ultrafine particulate materials, the treatment of surfaces, etc. Under normal pressures, the PPCP can raise the electron temperature for production of active chemical species, such as OH radical, O, O{sub 3}, O{minus}, O{sub 2}*, etc., without raising the ion temperature; this had been possible only by high-frequency glow discharge under low pressure. This paper reports on a reliable nanosecond-pulse high-voltage generator developed enabling continuous operation necessary to establish the PPCP as an industrial device.
