Customer ServiceEnergy 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.
In a Hybrid Energy System (HES), bidirectional converters are used to transfer energy between sources and batteries. These converters play an important role in supporting and recovering energy for the battery. The suggested converter has the feature of both bidirectional and multiport structures.
As energy transfer in either direction is required for the system, each dc-ac converter must also have bidirectional energy transfer capability. With the same token, the dc buses in this structure must also be able to either generate or absorb energy.
In the forward operation, the full-bridge network of the secondary side is used for synchronous rectification, meaning the bidirectional LLC resonant converter can realize both the ZVS of the primary side and the zero current switching (ZCS) of the secondary side under a certain gain range.
However, traditional LLC resonant converters are only used for unidirectional power transfer, and the introduction of LLC into bidirectional converters has become the focus of research due to the good soft-switching characteristics of the LLC, as shown in Figure 4.
