Abstract: The disclosure relates to a controller for a power converter, the power converter comprising a first switch and a second switch, wherein the controller is configured to receive a first control signal based on a first drain-to-source voltage of the first switch; receive a second control signal based on a second drain-to-source voltage of the second switch; derive a first switch control signal based on the first control signal and control the first switch by providing the first switch control signal to the first switch; derive a second switch control signal based on the second control signal and control the second switch by providing the second switch control signal to the second switch; wherein the first switch control signal and the second switch control signal each comprises turn-on edges and turn-off edges. Furthermore, disclosure also relates to corresponding methods, a non-transitory computer readable medium.
