Multiport AC-DC-AC Interfacing Converter for Microgrid Applications

Abstract

Integration of renewable energy resources into the existing power system has been increasing significantly in recent times. This paper presents an AC-DC-AC converter for integrating both AC and DC renewable energy resources into the power system using a single converter with reduced number of switches. The converter is compared against a similar existing topology for analysing the relative performance. A novel performance enhancement technique is proposed to minimize losses in the system. Application of the converter is depicted and verified through detailed simulation studies.
