Study on Power Injected Characteristics of Pulse Corona Discharge System

In process of pulse corona discharge, the asymmetric time characteristics in injection of energy from pulse power supply to reactor are studied in this article. The concepts of effective time and effective average power are defined and studied in a needle plate reactor with single needle. The consistent characteristics of pulse power and pulse current in time are also studied. Single pulse time distribution is from 0.01 s to 0.1 s. Average power distribution is from 5 W to 30 W. Effective time is about 10 μs. Effective average power distribution is from 15 kW to 60 kW. The effective average power is about 10~3 times of average power. And in effective time, energy injected into reactor is with huge power in course of pulse corona discharge. Effective average power is a kind of parameter to denote the process of energy injection in pulse corona discharge. It is a kind of ubiquitous characteristic in course of pulse discharge studied in this article.
