The topology of bidirectional LLC converters replaces the secondary rectifier network used in traditional LLC converters with a full-bridge network.
Bidirectional DC/DC converters enable charging of the battery in the forward mode of operation and facilitate flow of power back to the grid from the battery during reverse mode of operation, which can be used to stabilize the grid during peak load periods.
For safety, low-voltage battery pack systems (40V to 60V) require bidirectional isolation DC/DC due to the high bus voltage (360V to 550V). This article generally analyzes the advantages and disadvantages of different isolated bidirectional DC/DC topologies. Figure 1. DC-Coupled Energy Storage System
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.
The cabinets are cooled by a powerful air to air heat exchanger system with the ability to dissipate up to 1300W of heat. This uses temperature-controlled DC fans for lowest energy use and lowest possible
