Parameter Estimation Procedure for Models of Single-Phase Uncontrolled Rectifiers

Abstract

Low-power single-phase loads using single-phase uncontrolled rectifiers with dc-smoothing capacitors as their power supply are increasingly present in low-voltage distribution systems, causing high-voltage distortions. This paper studies the estimation procedure of single-phase rectifier parameters and presents an estimation algorithm based on a rectifier model and actual measurements. The model and the estimation procedure are described and validated with measurements in the laboratory and household installations, respectively.
