Abstract
Controller and method for a power converter. For example, a controller for a power converter includes: a first drive signal generator configured to generate a first drive signal and output the first drive signal to a first transistor configured to receive an input voltage and related to a primary winding coupled to an auxiliary winding and a secondary winding related to an output voltage; a second drive signal generator configured to generate a second drive signal and output the second drive signal to a second transistor coupled to the first transistor and related to the primary winding; a demagnetization detector configured to generate a demagnetization signal based at least in part on a first voltage related to the auxiliary winding, the demagnetization signal indicating an end of a demagnetization process; and a first controller configured to generate a first control signal.
