摘要
A method for regulating a switched-mode power supply includes steps of: providing a switched-mode power supply having at least one electronic switch and a drive circuit having an input receiving a primary current simulation, the switched mode power supply supplying a relatively higher output power at times and a relatively lower output power at other times; as an output load decreases, lowering a switching frequency to reduce switching losses; and starting the step of lowering the switching frequency during an occurrence of the lower output power by, during a switch-on interval of the electronic switch, deforming a rise in a voltage at the input for receiving the primary current simulation such that the voltage rises more steeply during a time segment.
