Abstract
A DC to DC converter that uses three switching devices and processes power in such a way that it can operate very efficiently. The converter only processes that portion of the input power that is required to provide regulation. In addition, by judiciously selecting magnetic components and turns ratios, the converter can be optimized for narrow input voltage ranges or for wide input voltage ranges. The converter operates in such a way that it can add or subtract energy on the primary side of the converter to achieve regulation.
