Abstract
Circuits and methods for controlling a converter are disclosed. A first switch within the converter can be turned off, and a second switch within the converter alternately can be turned on and off in response to a switch control signal while the first switch is turned off. By turning the second switch alternately on and off, energy stored in the converter can be recovered to a power source of the converter.
