Abstract
Switching-mode power conversion system and method thereof. The system includes a primary winding configured to receive an input voltage and a secondary winding coupled to the primary winding. Additionally, the system includes a compensation component configured to receive the input voltage and generate at least a clock signal based on at least information associated with the input voltage, and a signal generator configured to receive at least the clock signal and generate at least a control signal based on at least information associated with the clock signal. Moreover, the system includes a gate driver configured to receive at least the control signal and generate a drive signal based on at least information associated with the control signal, and a first switch configured to receive the drive signal and affect a first current flowing through the primary winding.
