Evaluation of pulse voltage generators

The electrical characteristics of the positive pulsed corona in a coaxial wire-cylinder-type reactor were investigated. The energy and charge injected into the discharging volume per pulse and per unit length of corona emitting wire are used to evaluate the power source, electric circuits, and corona wire. The discharge current lasts from several hundreds nanoseconds to a few microseconds. The current, power peak values and the injected energy and charge per pulse per unit emitting wire can reach up to 60 A/m, 5 MW/m, 480 mJ/m and 8 mu C/m, respectively. The energy conversion efficiency related to the delivery of output energy from the pulse forming capacitor to the discharging volume can reach 90%. All results were obtained at room temperature and in air.<>
