Generalized Feedforward Control of Single-Phase PWM Rectifiers Using Disturbance Observers

This paper presents a generalized feedforward control scheme for a single-phase boost rectifier, operating with indirect current control, to improve the dynamic response of its output voltage against line and load disturbances, as well as for changes in the reference voltage. Digital implementation of the control method is discussed. A small-signal model of the converter system is presented. The stability of the current loop at light loads is studied. A method is presented to estimate the input voltage and the load current without having to actually measure these quantities for the purpose of feedforward control. Simulation and experimental results are presented
