Energy Storage: The bidirectional capability of the proposed converter makes it ideal for use in energy storage systems. By efficiently managing the charge and discharge cycles of batteries, the proposed design can support more effective and reliable energy storage solutions.
Bidirectional Operation: The ability to operate bidirectionally is a key feature of the proposed design. This capability allows the converter to handle both DC-DC and DC-AC conversions seamlessly, making it versatile for various applications, including energy storage systems and grid-tied PV installations.
A comprehensive experimental process was adopted to validate the two modes of operation of the bidirectional DC–AC converter proposed here when connected to the AC grid and in a power range up to 1.5 kW.
In rectifier mode, the DC–AC stage acts as a full bridge while power factor correction (PFC) is provided by the DC–DC stage. The main contribution of this study is the sizing and experimental validation of the proposed bidirectional DC–AC converter topology coupled with a control strategy for HEMS applications.
The proposed bidirectional DC–AC converter can operate in a grid-connected configuration, with the ability to charge batteries during off-peak hours and use the energy from those batteries during peak loads. The operating mode of the entire converter is controlled by the previously presented HEMS system [ 23 ].
Gundabathini and Pindoriya 27 proposed an improved control strategy for bidirectional single-phase AC-DC converters in hybrid AC/DC microgrids, emphasizing the importance of seamless power flow between AC and DC systems.
A bidirectional four-port DC–DC converter for grid connected …
Most four-port converters typically enable bidirectional power flow through the low-voltage side battery port, which is used to discharge to the high-voltage side DC-link and charge from energy sources. However, system-level power management is restricted by the DC-link''s absence of bidirectional power transmission. This manuscript proposes a hybrid …
