Z-Source Dual Active Bridge Bidirectional AC-DC Converter for Electric Vehicle Applications

Abstract

This paper proposes an on-board AC/DC Bi-directional Converter intended to assist V2H and G2V operation for a commercially available 48V Electric scooter battery. The proposed topology utilizes the merits of DAB topology and IS network. The converter is best suitable when isolation between the vehicle and grid is necessary and when DC voltage boost is required to interface with home.
