Abstract
A ripple suppression circuit and a ripple suppression method for quasi-resonant flyback power supply. The ripple suppression circuit includes a compensation circuit and a control circuit, the compensation circuit configured to generate a compensation signal based on bus voltage, and the control circuit configured to compare a first signal and a second signal to provide a first control signal to control the power switch of the quasi-resonant flyback power supply turning from the on state to the off state. Wherein the first signal is compensated by the compensating signal. Compared with traditional power switch control mode of quasi-resonant flyback power supply, the ripple suppression circuit takes the bus voltage as a part of the first signal, and compares the first signal with the second signal, then controls the status of the power switch according to the comparison result.
