A digital implementation of a method for controlling line-commutated converters in discontinuous current is presented. The proposed strategy is based on the modification of the firing angle by means of an on-line estimation of the rectifier average current. Simulations and experimental results on a current control system are presented.
A method for controlling line-commutated converters in discontinuous conduction mode is presented. The proposed strategy is based on the modification of the tiring angle alpha in order to produce the same effects on the average output current regardless the conduction mode. The compensation is based in an on-line estimation of the rectifier average output current in order to achieve the compensation...
In this manuscript, a novel all-digital high-speed closed-loop thyristor hring system is presented. Different aspects associated to digital implementations, like sampling frequency, synchronism and finite word-length are analyzed. Experimental results obtained on a test supply are discussed.
