A unifying derivation of switching DC-DC converter topologies

Abstract

A canonical switching cell is proposed from which the three basic DC-DC converter topologies can be derived. In addition, it is possible to perform topological transformations which yield apparently new topologies. Upon examination, however, these topologies may prove to be identical to existing basic topologies. An optimum topology converter recently described by Cuk, et al.,is shown to be a transformation of a basic topology.
