Systematic Derivation of Two-State Switching DC-DC Converter Structures

Abstract

The new method of derivation of two-state dc-dc converter structures is proposed. In contrast to the available techniques this method originates from the set of general requirements concerning both structure and operation of a switching converter. These requirements coupled with an adopted definition of a minimal number of elements, are converted into the form of topological graph properties and applied in the proposed synthesis procedure. As a result, twelve basic two-state converter structures, including four new topologies, are obtained.
