System Accuracy Analysis of the Multiphase Voltage Regulator Module

摘要

The paper analyzes the system accuracy of the multiphase voltage regulator module and identifies the influential factors contributing to load line errors. The load line equations for a three-phase buck converter are derived and applied to the worst-case and root-sum-square analyses of load line accuracy. The calculation results are compared with SPICE Monte Carlo simulation, a more realistic statistical method of system accuracy prediction, and verified by the experimental results of the three-phase synchronous buck converter
