Power adapters generally include a few components that make up the majority of the volume. One component that can consume a relatively large volume is a bulk capacitor. In accordance with the implementations described herein, the size (which can include the capacitance value or volume) of the bulk capacitor within a power adapter can be reduced. Moreover, by introducing a new control scheme, the bulk capacitor can be eliminated from the power adapter. This size reduction or elimination of the bulk capacitor from a power adapter can result in not only a smaller power adapter, but can also result in a lower cost for production of the power adapter and/or an improvement in the power factor and/or power efficiency of the power adapter. This type of relatively small adapter can be beneficial from a user experience perspective.
