| Résumé : | This paper proposes a high-efficiency high-power-density voltage regulator (VR). An integrated magnetic self-driven full-bridge topology is employed as the main circuit. The proposed VR runs at a 700-kHz switching frequency for a 1 Unit Height (1U) form factor. A novel synchronous rectifier drive method is used to achieve high efficiency. The direct current resistance (DCR) current-sensing method is used for the integrated transformer to achieve adaptive voltage position. Compared with the traditional multiphase buck converter, the proposed solution has higher efficiency, a smaller passive component footprint, and a lower device cost. A 1U 700-kHz VR prototype is built in the laboratory, and it achieves 88.2% efficiency at a 1.2-V/130-A output. The experimental result verifies the theoretical analysis. |
