Abstract:
1. A switch-mode power conversion system, the system comprising: a primary winding configured to receive an input voltage; a secondary winding coupled to the primary winding and configured to, with one or more other components, generate an output signal; a feedback component configured to receive the output signal and generate a feedback signal based on at least information associated with the output signal; a voltage detector configured to receive the input voltage and output a detection signal; a mode controller configured to receive the detection signal and the feedback signal and generate a switch signal based on at least information associated with the detection signal and the feedback signal; and a switch configured to receive the switch signal and affect a first current flowing through the primary winding; wherein the mode controller is further configured to: wherein the switch signal corresponds to the operation mode for the switch-mode power conversion system.
