Abstract
In some examples, a method of controlling a first switch and a second switch of a resonant mode power converter circuit, the method comprising delivering control signals to the first switch and the second switch at a switching frequency. The method also comprises determining, for a first driving period, a first phase relation between a phase of a resonant current in the resonant mode power converter circuit and a phase of the control signals. The method further comprises determining, for a second driving period, a second phase relation between a phase of the resonant current and a phase of the control signals, and controlling the switching frequency based on a difference of the first phase relation and the second phase relation.
