Abstract
In accordance with one embodiment, an observed power transfer is estimated based on input and output voltage measurements associated with an observed power transfer from the primary converter to the secondary converter. An electronic controller or electronic data processor determines a ratio or percentage between the observed power transfer and maximum power transfer. A load curve is selected based on the determined ratio or percentage. The modulation frequency is adjusted or maintained for of the primary converter and the secondary converter consistent with an operation point on the selected load curve, where the operation point minimizes the power loss, power difference, or thermal energy dissipated from the converter.
