Abstract

See full text

A system for plasma ignition and maintenance of an atmospheric pressure plasma. The system has a variable frequency alternating current (AC) power source, a transformer, a cable connected to a secondary winding of the transformer, a programmed microprocessor for control of power to the atmospheric pressure plasma. The microprocessor is configured to a) at pre-ignition, power the AC power source at an operational frequency fop higher than the resonant frequency fr, b) decrease the operational frequency fop of the AC power source until there is plasma ignition, and c) after the plasma ignition, further decrease the operational frequency fop of the AC power source to a frequency lower than the resonant frequency fr.
