Abstract:
The present invention proposes a control circuit and a method of controlling a resonant converter comprising a full-bridge configuration in the following manner: during each half period of a plurality of periods of a resonant current of the resonant converter, starting from an initial state ( 500 ) in which a diagonal pair are conductive, turning off ( 510 ) a first switch member of the diagonal pair on the basis of the voltage control signal; turning on ( 520 ), after the turn-off of the first switch member, a switch member in series connection with the first switch member prior to a zero crossing (E 5 ) of the resonant current; turning off ( 530 ), after the turn-off of the first switch member, a second switch member of the diagonal pair prior to the zero crossing (ES); and turning on ( 540 ), after the turn-off of the second switch member, a switch member in series connection with the second switch member prior to the zero crossing event of the resonant current.

Claim (Index 15):
An x-ray generator, comprising:\n a power inverter comprising:\n a resonant converter comprising:\n a full-bridge configuration, the full-bridge configuration comprising two parallel switching branches, each of the two switching branches comprising two series-connected switch members, a switch member of one switching branch and a respective member of the other switching branch forming a diagonal pair; and \n a resonant circuit connected between junctions (A, B) of the two series-connected switch members of each of the two switching branches; and \n \n a control circuit for controlling the resonant converter, comprising:\n an output voltage controller for providing a voltage control signal for controlling an output voltage of the resonant converter; \n a switch encoder for controlling switching events of the switch members, wherein the switch encoder is configured, during each half period of a plurality of periods of a resonant current of the resonant converter, starting from an initial state in which a diagonal pair are conductive, to:\n turn off a first switch member of the diagonal pair on the basis of the voltage control signal; \n turn on, after the turn-off of the first switch member, a switch member in series connection with the first switch member prior to the zero crossing of the resonant current, on the basis of the zero crossing event; \n turn off, after the turn-off of the first switch member, a second switch member of the diagonal pair prior to the zero crossing, on the basis of the zero crossing event; and \n turn on, after the turn-off of the second switch member, a switch member in series connection with the second switch member prior to the zero crossing event of the resonant current, on the basis of the zero crossing event; \n \n \n a DC voltage source connected to an input of the power inverter; and an x-ray tube connected to an output of the power inverter.
