Repetitive pulse power system for pulsed corona gas treatment research

Summary form only given, as follows. A pulsed power generator for pulsed corona gas treatment research is presented. In order to fulfill the required electrical parameters, four basic pulsed power techniques are used: magnetic pulse compression, pulse transformer, high voltage pulse forming line, magnetic switching. The first capacitor is resonantly charged. The charging time allows up to 1000 charges per second. The primary switch is a 25 kV thyratron, working in safe conditions (8 kV, 6 /spl mu/s, 60 A maximum, 1000 Hz). After a magnetic compression (from 6 /spl mu/s to 500 ns), the pulse amplitude is raised to 60 kV with a pulse transformer. A high voltage pulse forming line and a final magnetic switch create the final electromagnetic pulse to supply the pulse corona reactor: 30 kV, 100 ns, 600 A. The maximum average load power, for 1000 pulses per second, is 1.8 kW. These parameters are compatible with a pulsed corona gas treatment laboratory research (the optimum gas flow rate is around 1 l/min). In the same time, the described system can be quite easily scalable for industrial needs.
