TI’s bidirectional dual active bridge reference design is a 10kW reference design that includes an isolated bidirectional dual active bridge DC/DC converter. The main targets for this reference design are power-conversion systems for energy storage or DC charging piles. The design supports an input voltage range of 700V to 800V, which is in the range for a typical microgrid DC bus voltage, making it a good fit for powering distributed loads and integrating battery backup systems.

The reference design achieves a power density of 2.25kW/L by using a high-performance control circuit that drives SiC power MOSFETs. The symmetrical structure in the dual active bridge allows converter stacking to achieve even higher power throughput, and the bidirectional design enables flexible energy transfer between the battery storage and the DC bus. Figure 4-2 is a block diagram of the system components.
