|Abstract:||This paper presents a dual frame control scheme with a digital plug-in frequency domain based repetitive controller (FDRC) for minimizing the even order harmonics at the output dc link voltage and odd order harmonics in the line currents under the distorted and unbalanced supply voltage conditions. In the proposed control scheme, the algorithm of the reference current calculation is to make sure that the dc link voltage is maintained constant and the supply side power factor is kept close to unity. The plug-in repetitive controller is designed to achieve line side currents with low THD for the three phase PWM boost rectifier. The experimental test results obtained from a 1.6 kVA laboratory based PWM rectifier confirm that the ripples at the dc link voltage can be reduced to 0.5% and the THD of the line side current can be minimized to 3.75% by using the proposed control scheme. ©2008 IEEE.|
