Toroidal low-field reactive gas source

摘要

An apparatus for dissociating gases is provided the apparatus comprising: a. a plasma chamber (20;100) comprising a gas; b. a transformer (12) having a magnetic core (16) surrounding a portion of the plasma chamber and a primary winding (18); and c. a solid state AC switching power supply comprising one or more switching transistors (268) coupled to a voltage supply (256) and having an output coupled to the primary winding, the solid state AC switching power supply driving an AC current in the primary winding, the current inducing an AC potential inside the chamber that directly forms a toroidal plasma (270) that completes a secondary circuit of the transformer and dissociates the gas.
