Abstract
A system for powering a dual magnetron with a dual power supply is disclosed. A first power supply supplies a first voltage to a first magnetron. A second power supply supplies a second voltage to a second magnetron. A balancer circuit controls a drive current for altering a magnetic field of the first magnetron and a magnetic field of the second magnetron to maintain the first voltage and the second voltage at a substantially equal voltage.
