Abstract
Controller and method for charging one or more loads. For example, the controller for charging one or more loads includes: a controller terminal configured to be biased at a first voltage related to a second voltage of a secondary winding of a power converter, the power converter further including a primary winding coupled to the secondary winding, the power converter being configured to, if the power converter is not unplugged from a voltage supply for an AC input voltage, receive the AC input voltage represented by the second voltage and output an output power to the one or more loads; and a voltage detector configured to: process information associated with the first voltage; and determine whether the AC input voltage is in a first voltage state or in a second voltage state based at least in part on the first voltage.
