Abstract:
1. A system for regulating an output voltage of a power conversion system, the system comprising: an error amplifier coupled to a capacitor, the error amplifier being configured to receive a reference voltage, a first voltage, and an adjustment current and to generate a compensation voltage with the capacitor, the first voltage being associated with a feedback voltage; a current generator configured to receive the compensation voltage and generate the adjustment current and a first current; a signal generator configured to receive the first current and a second current, the signal generator being further configured to receive a sensing voltage and to generate a modulation signal; and a driving component configured to generate a drive signal based on at least information associated with the modulation signal and output the drive signal to a switch in order to affect a third current flowing through a primary winding of a power conversion system; wherein: wherein:
