(2) Bi-directional DC-DC Platform
CLLC topology is employed to realize the isolated bidirectional power conversion in this reference design, which has the advantage of zero-voltage-switching (ZVS) in full load range for high efficiency and high power density. The electric energy could be transferred bidirectionally with one set of the hardware for cost saving and volume reduction. The NXP DSC MC56F83783 is used to enable the fully digital control of the power system. With the help of the DSC’s flexible peripherals, the synchronous rectifier could be realized simply for BOM cost saving.
