  • Double resonance high voltage converter with start-up
    Patent number: 6834000
    Abstract: A double resonance voltage converter and method of operating such a converter having: a switching circuit with a first switch and a second switch; a double resonance resonant circuit having a series resonant circuit and a parallel resonant circuit; a rectifying and filtering circuit, and a control circuit for controlling the switching circuit having two state arrangements. A first arrangement controls the conducting states of the switching circuit and a second arrangement controls the start of the first arrangement. The converter may be used to obtain very high voltages, on the order of 100 kilovolts and more, for providing power to an X-ray tube in a radiological imaging apparatus.
    Type: Grant
