Control of an AC Chopper by a Digital Signal Processor using a Processor-in-Loop Arrangement

Abstract - This document is aimed to present a processor-in-loop arrangement using the synchronous reference frame controller operating on an ac chopper for reactive and harmonic compensation. The controller is detailed taking into account the mathematical expressions of the converter, and how these shape its structure. The different harmonic components generated by the converter and how these are produced by specific duty-cycle components is also exposed. Finally, the implementation in a digital signal processor using a processor-in-loop arrangement to obtain transient- and steady-state signals aid in assessing the performance of the controller in cancelling both the reactive and selected harmonic components. Keywords: AC Chopper, Synchronous Reference Frame, Processor-in-Loop Arrangement.
