Abstract
A controller for a power converter and method of operating the same. In one embodiment, the controller includes an inductor-inductor-capacitor ('LLC') controller configured to receive an error signal from an error amplifier to control a switching frequency of an LLC stage of the power converter to regulate an output voltage thereof. The controller also includes a power factor correction ('PFC') controller configured to control a bus voltage produced by a PFC stage of the power converter and provided to the LLC stage so that an average switching frequency thereof is substantially maintained at a desired switching frequency.
