Abstract
Controlling switching frequency of LLC resonant power converters. At least one example embodiment is a method of operating LLC converter, including: measuring values indicative of current through a primary winding of a transformer of an LLC converter, the measuring during a first on-time of a first switching period of an electrically controlled switch coupled to the primary winding, and the measuring creates a current waveform; calculating a slope of the current waveform; and controlling frequency of switching the electrically controlled switch based on the slope.
