Control of a PWM Rectifier with Extended Functions in a Signal Digital Processor

Abstract

THIS WORK PRESENTS THE APPLICATION OF A DIGITAL SIGNAL PROCESSOR (DSP) FOR THE CONTROL OF A THREE-PHASE PWM RECTIFIER FOR INDUSTRIAL APPLICATIONS, TO WHICH ARE EXTENDED THEIR FUNCTIONS TO HAVE CAPACITY TO COMPENSATE VOLTAGE SAGS. THE STUDY STANDS OUT THE ADVANTAGES THAT THE DSP OFFERS TO CONTROL, BASED ON THE SYSTEM TRANSFORMATION FROM FIX REFERENCE FRAME TO SYNCHRONOUS REFERENCE FRAME (D-Q THEORY) AND CLASSICAL CONTROLLERS. THE ANALYSIS OF THE SYSTEM IS PRESENTED, AS WELL AS SIMULATION AND EXPERIMENTAL RESULTS TO VALIDATE THE OPERATION OF THE DSP AS SYSTEM ELEMENT CONTROLLER.
