An article briefly describes advantages of streamer form of corona discharge over corona discharge of direct voltage. With the purpose of confirmation of hypotheses about possibility of stabilization of discharge processes in electric fields of streamer form of corona discharge oscillography voltage and current were done, and volt amperage features at various frequencies of pulse voltage were taken. Impact of parameters of electrodes system «Potential plane with corona needles – grounded plane» to value of discharge current was studied. Outcomes of study of power features and character of change in strength of electric fields of streamer form of corona discharge are presented.
Based on an analysis of the processes in the supply circuit of ozone generators with periodic sinusoidal and pulsed voltages of high duty cycle, it is revealed that when powered by a sinusoidal voltage, a significant part of the energy consumed is spent on heat loss. Only in a small part of the sinusoidal voltage, namely in the zone of reaching the amplitude value, a barrier discharge occurs with the generation of ozone. Therefore, the efficiency ozone generators at sinusoidal voltage do not exceed 2%. When powered by a pulsed voltage, ozone generation occurs almost during the application of the entire voltage pulse; in addition, ozone generation also occurs in the pause between pulses, due to oscillatory processes in the pause between pulses. In addition to a significant increase in ozone yield, there is practically no process of heating the dielectric barrier.

This article analyzes the existing ways of creating cold plasma at atmospheric pressure directly into atmospheric air. Research areas listed turns out to be very valuable from a practical point of view, since allows you to create in the plasma gas enough intense ultraviolet radiation, as well as high concentration of physically and biochemically active particles (metastable atoms and molecules, radicals, ozone and other reactive compounds) relatively small specific energy costs. Further in the article, a theoretical comparative analysis of the processes of ozone electrosynthesis in electric sinusoidal and pulsed electric fields is given. The revealed advantage of pulsed electric fields is confirmed by the results of experimental studies
