Abstract
Power converter controllers, flyback converters and methods are provided which use a resonant tank current of the flyback converter as a measure for an output current of the flyback converter. A power converter controller includes a control logic circuit that is configured to use, as a measure of an output current of the flyback converter, the resonant tank current indicated by the signal at a time in a phase where there is no reflected current to the primary side of the flyback converter.
