Publication/Patent Number: US10199944B2 Publication Date: 2019-02-05 Application Number: 15/849,438 Filing Date: 2017-12-20 Inventor: Fang, Lieyi   Lin, Guo Wei   Assignee: Guangzhou On-Bright Electronics Co., Ltd.   IPC: H02M3/335 Abstract: System and method for regulating a power converter. The system includes a comparator configured to receive a first signal and a second signal and generate a comparison signal based on at least information associated with the first signal and the second signal. The first signal is associated with at least an output current of a power converter. Additionally, the system includes a pulse-width-modulation generator configured to receive at least the comparison signal and generate a modulation signal based on at least information associated with the comparison signal, and a driver component configured to receive the modulation signal and output a drive signal to a switch to adjust a primary current flowing through a primary winding of the power converter. The modulation signal is associated with a modulation frequency corresponding to a modulation period.
