Abstract
An LLC converter includes an input having a first node and a second node. A first switch is coupled between the first node and a third node and a second switch is coupled between the third node and the second node. A transformer having a first transformer input is coupled to the third node. A resonant capacitor is coupled to a second transformer input and a first input of a summer. A voltage ramp generator is coupled to a second input of the summer, the summer for summing voltages at the first input and the second input. The converter further includes circuitry for generating control signals for the first switch and the second switch in response to the output of the summer.
