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 () in which a diagonal pair are conductive, turning off () a first switch member of the diagonal pair on the basis of the voltage control signal; turning on (), 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) of the resonant current; turning off (), 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 (), 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.
