Abstract
At a switch terminal of a flyback converter in a discontinuous conduction mode in a power meter, an apparatus determines a resonant frequency of the flyback converter. The apparatus determines whether the resonant frequency satisfies a condition. Through a controller, the apparatus triggers an event responsive to determining that the resonant frequency satisfies the condition.
