Abstract
Technologies are described for an adaptable power supply that can switch between two or more output voltages. The power supply includes discharge circuitry that utilizes the secondary windings of a transformer as a discharge path when the power supply switches from a high voltage level to a low voltage level. In some embodiments, the discharge circuitry is included within a synchronous rectifier. In other embodiments, the discharge circuitry is separate from the synchronous rectifier. In still other embodiments, the power supply does not include a synchronous rectifier. Whichever embodiment is used, an output capacitor can be discharged through the secondary windings of a transformer and the transformer can store that energy for future use.
