Title

Non-Isolated Half Bridge Buck Based Converter For Vrm Application

Abstract

High efficiency and fast transient response are very critical to Voltage Regulator Module (VRM) and they are contradicted to each other. Continuous output voltage drop with increased current and power densities force small duty cycle operation, resulting in lower efficiency and worse transient response. This paper presents a new, transformer based, non-isolated, buck derived, half bridge converter for VRM application. The transformer in the presented topology helps in decreasing the top switch current as well as the bottom switch voltage stresses, it also extends the duty cycle to a favorable range enhancing the efficiency and transient response by optimizing MOSFET selections. The proposed converter is designed, analyzed and the experimental results are presented. © 2007 IEEE.
