Claim Text:
1. A system for regulating a power converter, the system comprising: a ramping signal generator configured to receive a demagnetization signal and generate a ramping signal; a first comparator configured to receive the ramping signal and a first threshold signal and generate a first comparison signal based on at least information associated with the ramping signal and the first threshold signal; a second comparator configured to receive a sensed signal and a second threshold signal and generate a second comparison signal, the sensed signal being associated with a first current flowing through a primary winding of the power converter; and a modulation-and-drive component configured to receive the first comparison signal and the second comparison signal and output a drive signal to a switch, the switch being configured to affect the first current flowing through the primary winding; wherein: wherein: wherein:
