Abstract
A controller for a resonant converter is provided. The resonant converter includes a first switch, a resonant tank coupled to the first switch at a switching node, and a first capacitor. The controller is configured to operate in a first mode by providing a plurality of first periodic control pulses to drive the switching of the first switch at a first switching frequency. The controller is further configured to operate in a second mode by providing the plurality of first periodic control pulses to drive the switching of the first switch at a second switching frequency, the second switching frequency being less than the first switching frequency, or stopping providing the first periodic control pulses, and providing one or more first charging pulses, each of the one or more first charging pulses driving the switching of the first switch to charge the first capacitor.
