摘要

A reduced-order (RO) small-signal model of three-phasenpulse-width-modulation (PWM) rectifiers is proposed. By combining thenPWM switch model and equivalent multimodule model techniques in DC-DCnconverters, a three-phase rectifier can be modeled as a DC-DC converternwith equivalent power capability and small-signal characteristics. Thisnmodel reduces the system order to two and greatly simplifies the controlndesign and system analysis of three-phase converters. In this paper, thenproposed model is also used for control design and for systemninteraction analysis on the three-phase interface of a boost rectifier.nThe RO model is verified with the d-q model, switching-model simulation,nand experimental results
