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.
