Simulation study of the three-level boost DC-DC converter with full ZVS for PV application

Abstract

This paper presents the full zero voltage switching three-level boost dc-dc converter. The boundary conduction mode and snubber capacitors provide zero voltage switching operation in the whole range of operation. Analytical estimation and simulation results have proved the proposed idea. In advance, it was demonstrated that the multi-cell structure along with an interleaved control technique provide high efficiency performance and continuous input current that makes it a promising solution for photovoltaic applications.
