Abstract
A control circuit controls a switching circuit of a resonant converter where the switching circuit includes first and second power switches. A first on time of the first power switch and a second on time of the second power switch are controlled to generate a square wave signal to drive the resonant circuit. The control circuit controls the first on time based on a zero current detection time indicating detection of a zero current crossing of a resonant current generated in the resonant circuit in response to the square wave signal and on a time shift delay time based on an output voltage of the resonant converter. The second on time of the second power switch control is based on the zero current detection time detected for the first power switch and on the time shift delay time.
