This paper presents the design and testing of an LLC DC transformer (DCX) capable of directly converting power from a regulated 48 V DC bus to the point of loads (PoLs). By using series connected transformer windings and parallel connected rectifiers, the proposed LLC DCX has achieved high voltage conversion ratio (48:1) and high output current (>300A) within a 58 by 15 by 5.6 mm volume. The design of the high-frequency transformer is introduced and a 48-to-IV DCX prototype with 300A output current is constructed, exhibiting a peak efficiency of 93.7% and a full load efficiency of 89.0%.
期刊介绍:
COMPEL exists for the discussion and dissemination of computational and analytical methods in electrical and electronic engineering. The main emphasis of papers should be on methods and new techniques, or the application of existing techniques in a novel way. Whilst papers with immediate application to particular engineering problems are welcome, so too are papers that form a basis for further development in the area of study. A double-blind review process ensures the content''s validity and relevance.
