Abstract
A ballast transformer and system using the ballast transformer to couple power to a plasma load. The ballast transformer has a magnetic core, a first primary winding on a primary side of the magnetic core, a secondary winding on a secondary side of the magnetic core, and a second primary winding connected in series with the first primary winding and wound in proximity to the secondary winding on the secondary side of the magnetic core. The first primary winding is connectable to the AC power source, and the secondary winding is connectable to the plasma load via a coaxial cable.
Claims20
A system for coupling power to a plasma load, comprising:
- an alternating current (AC) power source;
- a ballast transformer having
- a magnetic core,
- a first primary winding on a primary side of the magnetic core and connected to the AC power source,
- a secondary winding on a secondary side of the magnetic core, and
- a second primary winding connected in series with the first primary winding and wound coaxial to the secondary winding on the secondary side of the magnetic core;
- and
- a coaxial cable for connecting the secondary winding to the plasma load.
A method using any of the system statements above for providing power to a plasma, the method comprising:
- providing power from an AC power source to a plasma load via the asymmetric ballast transformer in any of the statements above having a sufficient leakage inductance to prevent current surges;
- and
- igniting and developing a steady state atmospheric pressure plasma.
