Active Input Line Current Shaping using Support Vector Machines

A strategy to minimize the harmonics injection to the mains, generated by static converters and further correcting power factor is adding to the converter an active current waveform shaper block based in a step-up dc-dc converter; the typical control scheme shows the disadvantage of being highly no-linear. In this paper is described an alternative control scheme based in "support vector machines" (SVM). SVM are algorithms of emergent computation that have demonstrated an excellent acting in classification and regression applications. This study case showed the correct performance and interesting results as control block, for the case of a full-bridge, single-phase rectifier under computer simulation
