Abstract

This study investigates parallel structure general repetitive control (PSGRC) and its error convergence rate by using exponential function properties. PSGRC offers a general repetitive control solution for power converters to mitigate power harmonics distortions. PSGRC with appropriate settings will lead to various RCs with various error convergence rates at interested harmonic frequencies, e.g. conventional RC, dual-model RC, and odd harmonics RC. As application examples, PSGRC was applied into general grid-connected pulse-width-modulation (PWM) converter systems. Experimental results show the effectiveness and advantages of PSGRC: three/single-phase grid-connected PWM converters can achieve zero-error current tracking and very fast current error convergence rate upon demand.
