Abstract

This paper presents a hybrid multitrack converter with the capability of partial power regulation. This converter incorporates the merits of the Multitrack converter and Sigma converter. The input power is distributed and transferred by a DC transformer (DCX) and a two-stage circuit, whose front stage is a PWM converter to realize voltage regulation and the next stage works as DCX. The two DCXs are integrated into one transformer. The proposed converter realizes reduced device ratings, partial power regulation and integrated transformer. A 32-75V input, 5V, 20A output isolated dc-dc converter for data center applications is built to verify the effectiveness of the proposed circuit structure. The peak efficiency of 95.1% is achieved at 48V nominal input voltage with 190W/inch³ power density.
