Abstract
A method for controlling a power converter includes determining whether a value of a feedback signal is in a first range, detecting a plurality of points of the feedback signal, and decreasing one or both of a proportional coefficient and an integral coefficient of a first control loop of the power converter at a first plurality of times corresponding to the detected plurality of points of the feedback signal when the value of the feedback signal is in the first range. The feedback signal indicates an output signal of the power converter. A circuit for controlling a power converter includes a transient detector that generates a transient detection signal in response to a feedback signal indicating an output signal of the power converter and a gain selector that generates a gain selection signal in response to the transient detection signal.
