Abstract:
1. A system controller for regulating a power conversion system, the system controller comprising: an error amplifier configured to receive an input signal and a first reference signal and generate an amplified signal based on at least information associated with a difference between the input signal and the first reference signal; a compensation component configured to receive the amplified signal and generate a second reference signal based on at least information associated with the amplified signal; a summation component configured to receive the second reference signal and a predetermined reference signal and generate the first reference signal, the first reference signal being equal to a sum of the second reference signal and the predetermined reference signal, the first reference signal being different from the second reference signal; a signal generator configured to receive at least the amplified signal and generate one or more control signals based on at least information associated with the amplified signal; and a driving component configured to receive the one or more control signals, generate a drive signal based on at least information associated with the one or more control signals, and output the drive signal to a switch to affect a first current flowing through a primary winding of a power conversion system.
