Synthesis Methodology for Multipole ZVT Converters

Abstract

This paper proposes a novel synthesis methodology to generate integrated zero-voltage-transition (ZVT) topologies, as well as to systematize the topologies that are already known. An approach is presented to classify single-pole ZVT converters. This approach can be expanded to multipole systems, such as polyphase inverters and rectifiers, uninterruptible power supplies, and variable-speed drives. The connections among several presented topologies are easily seen by means of the general diagrams that are shown in this paper. Analysis and understanding of the advantages, disadvantages, merits, and limitations of each converter are made easier since these converters are obtained from a common approach that is presented in this paper
