In the energy storage systems, a bidirectional AC/DC converter with a proper charging/discharging profile istypically required to transfer energy between the energy storage and the AC grid. The non-isolated single stage topologies are the simplest and most efficient for the interfacing of energy storages with AC systems.
This power converter is usually known as a two-port converter due to theinput port that connects to the energy source and the output port that connects to the load. However, there are systems that require the energy to be processed from multiple energy sources or to a multiple load, , , .
To interconnect these systems to the electrical network, it is required to usepower electronic interfaces. Various power electronic converters for the interface between the electrochemical energy storage system and the electrical network have been described. These power converters are divided into standard, multilevel and multiport technology.
The control system of a multiport converter is characterized by a typicalmulti-input multi-output (MIMO) structure, where normally the output voltages and source currents are controlled. The system control variables are the phase shifts and duty cycles.
In the charging mode of energy storage, the converter works as the SEPIC converter and in the discharging mode as the Luo converter. The SEPIC/Luo converter does not reverse the voltage and needs a transfer capacitor with lower voltage rating than that of the Cúk converter.
The topology was derived from the well-known three-to-three AC/AC matrix converter.It has a low-pass LC filter between the DC terminals and the DC source/load terminals, with no intervening impedance except for snubbers and wiring . Both polarities of voltages and currents may be controlled during the bidirectional operation of the converter.
