Study of a Multi-Port DC-DC Converter for an Energy Storage System

A multi-port DC-DC converter has been studied in paper. It can be used both in energy storage systems and in power supplying systems with several sources. A high-frequency transformer integrates the converters of the multiport converter. For converters, circuits with specific characteristics are used - resonant inverters with voltage limitation on the part of resonant capacitor. They can work as bidirectional converter. The paper describes the modes of operation of the converter in different directions of energy transmission. Results of research through simulation models are presented.
