The series resonant dual-active-bridge (SR-DAB) DC/DC converter reference design offers advantages like soft-switching, lower circulating current and high efficiency. The design is beneficial where power density, cost, galvanic isolation, wide-gain range, and high efficiency are needed for portable power stations and energy storage applications. This design illustrates control of the power topology using a C2000™ MCU in closed current-loop mode, which supports the bidirectional operation to support battery charging and discharging applications.
