Abstract

In this paper, a novel voltage and current sensorless control method (VCSC) for three-phase active front-end rectifier (AFR) is proposed. The proposed method is based on estimating the missing measurements based on a state feedback observer (SFO) and provides these estimates as feedback signals to a sliding mode controller (SMC). The proposed approach supports both current and voltage sensorless modes, where grid voltages are estimated based on the measured grid currents and vise-versa. Moreover, the estimation process requires only two voltage or two current sensors instead of three. The proposed VCSC is applied to a three-level three-phase T-type rectifier and implemented using MATLAB/Simulink. The obtained results demonstrate the ability of the proposed control to estimate the unavailable measurements, and in the worst case to enable the rectifier operate with only two sensors.
