Design of a Redundant Paralleled Voltage Regulator Module System with Improved Efficiency and Dynamic Response

Abstract

This paper discusses the design of true redundant, N+l parallel voltage regulator module (VRM) system with low droop resistance. Average current mode control and limited gain for voltage compensation is used to achieve droop current sharing between parallel modules without single point failure. Small signal model of the current sharing scheme is derived and… (More)
