  • System for powering dual magnetrons using a dual power supply
    Patent number: 10314120
    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.
    Type: Grant
    Filed: May 3, 2016
    Date of Patent: June 4, 2019
    Assignee: Heraeus Noblelight America LLC
    Inventors: Mahmood Gharagozloo, Ta Hai Yeh, Pradyumna Kumar Swain
