摘要
According to some aspects of the present disclosure, switched-mode power converters and control methods are disclosed. Example power converters include an input terminal, an output terminal, and a transformer coupled between the input terminal and the output terminal. The transformer includes a primary winding and a secondary winding. The power supply also includes at least one switch coupled to the primary winding, and a primary controller coupled to the at least one switch to control switching operation of the at least one switch. The primary controller includes a voltage reference. The power supply further includes a secondary controller configured to detect a no load condition at the output terminal, and operate the primary controller in a burst mode by adjusting the voltage reference of the primary controller when the secondary controller detects the no load condition at the output terminal.
