Electrical circuit topologies for pulsed corona plasma generation

摘要

This paper discusses novel pulsed circuit topologies for pulsed corona plasma generation. As a general principle, decrease of output impedance of pulsed power source leads to scale up of corona plasma power. DC superimposed pulse energization provides advantages of decrease of switching duty, increase of average power, and improvement of matching. Critical circuit elements include pulse forming networks (PFNs), triggered spark-gap switches and transmission line transformers (TLTs). Two main circuit topologies are based on single and multiple switches. The TLTs are used for both impedance matching and synchronization of the multiple switches.
