Abstract
The power consumption in data centers continues increasing, thereby pushing the converter to achieve high efficiency and high power density. This paper presents an asymmetrical half-bridge flyback converter for data center applications. Compared with an active clamp flyback converter, it functions as an isolated buck converter, and is more preferable for voltage step-down applications. The operating principle and the design considerations are included in this paper. An interleaving winding layout with uniformed current distributions is used for the planar transformer design. The built prototype satisfies an industrial standard low-profile sixteenth brick requirement, and achieves 94.9% peak efficiency and 468W/inch3 power density.
