Abstract
In this paper, a Vienna type boost rectifier is discussed and controlled using sliding mode control. Grid side's voltages are considered distorted and unbalanced. Sliding mode control function is defied to control the DC output voltage and AC input power factor. In order to produce proper reference voltage, the sampled voltage is applied to orthogonal system. The object of this system is to remove the distortions and produce sinusoidal reference voltage. Using pure sinusoidal reference voltage enables the control system to perform better in terms of power factor correction and DC output voltage regulation by eliminating distortions. The presented simulation results show the validity and effectiveness of proposed control method of three-phase Vienna rectifir under utility side distortion.
