Mathematical Description of AFE Rectifier Closed Loop System

This article address a mathematical description of a closed loop system of an active front-end (AFE) rectifier. The AFE rectifier has been considered as a two-dimensional linear object and its mathematical description has been presented. Synthesis of regulators have been carried out by the step-by-step correction principle. The mathematical model has been made in Matlab/Simulink program. The mathematical description of AFE rectifier as an object of controlling allows us to conclude that it is complex nonlinear system, and the synthesis of control system should be carried out based on the linear model for referents operation conditions.
