Abstract
A controller for a power converter and method of operating the same. In one embodiment, the controller includes a primary peak current circuit configured to produce a reference voltage corresponding to a primary peak current through a primary winding of a transformer of a power converter, and an offset corrector configured to provide an offset voltage to compensate for delays in the power converter. The controller also includes a summer configured to provide an offset reference voltage as a function of the reference voltage and the offset voltage, and a comparator configured to produce a signal to turn off a power switch coupled to the primary winding of the transformer as a function of the offset reference voltage.
