Bidirectional dual-active-bridge DC-DC converter for vehicle-to-grid applications in DC microgrids

摘要

This paper covers the application of a Dual-Active-Bridge (DAB) DC-DC Converter in Vehicle-to-Grid (V2G) technology for DC Microgrids. It comprises of a detailed study of the converter's behavior in order to achieve soft-switching in the whole operating range independently of the electric vehicle's battery state-of-charge while also ensuring stability of the Microgrid voltage port regardless of load or generation conditions.
