Multiphase voltage regulator module with self-driven synchronous rectification

This paper propose a multiphase voltage regulator module (VRM) based on the symmetrical half-bridge topology employing the single winding self-driven synchronous rectification (SWSDSR) scheme. Main advantages of the proposed VRM are the fast transient response and the simplicity in the driving of the synchronous rectifiers. Proposed VRM was evaluated on a 48 V/1.5 V, 60 A 4-phases VRM. Design considerations as well as experimental results are included in the paper.
