AC-AC Converter Topologies for Power Applications

Abstract

Power electronic converters are an essential component of modern power system. They are used due to their advantages in various applications like power system stability and reliability, reducing weight and size of the system, improving system life, etc. This paper overviews various AC-AC converter topologies, starting with AC choppers, including converters with and without energy storage elements. Further, different matrix converter topologies for power conversion, e.g. single-phase, three-phase, and multilevel matrix converters, are introduced to provide a quick overview. Subsequently, direct, indirect, and hybrid matrix converter circuits are considered. Various individual converter topologies are reviewed and compared to provide one-stop information.
