Abstract: An automatic tuning system for a magnetic field generating tuned circuit includes a processor configured to maintain the resonant frequency of a tuned circuit equal to a reference frequency. The tuned circuit is driven by a power amplifier whose output provides an amplified signal at the reference frequency. The tuned circuit includes a magnetic field generating inductor and a bank of individually switchable capacitors controlled by the processor capable of adding and removing the respective capacitances to and from the tuned circuit. The inductor includes a Faraday shield to shield the tuned circuit from the influence of electric fields. In an embodiment of the invention, the variable capacitor is in the form of a diode variable capacitor (varicap) in parallel circuit relationship with the tuned circuit capacitor and the inductor.

Abstract: A solid-state power processor circuit and method is used to supply power to generate a discharge in a corona discharge pollutant destruction apparatus. The circuit uses field effect transistors (FETs) and integrated circuit devices based upon metal oxide semiconductor field effect transistor (MOSFET) technology to amplify low-voltage pulse signals to high voltage levels. A resonator in the power processor circuit generates sinusoidal oscillation from the high voltage pulses, and provides the high-voltage, high-frequency electrical power necessary for corona discharge.
