Abstract

Controlled rectifiers are electronic power devices aimed at reducing the harmonic pollution in electrical networks caused by the power conversion process. The main goal is to obtain a sinusoidal shape current in phase with the voltage network. Although Proportional Integral controllers are widely used for the current control loop, they do not provide high performance results. On the contrary, Resonant and Repetitive Control are techniques with remarkable results on this area. However, their main drawback is the lost of performance due to frequency changes in the exogenous signal. In this work, the implementation of an Odd Harmonic High Order Repetitive Controller is proposed for the rectifier current loop. The odd harmonic characteristic of this compensator makes possible to obtain a computational burden that is very similar to the one obtained by conventional repetitive controllers with the advantage of increase the robustness against frequency variations. Experimental results show the high performance obtained even when the network frequency does not match the designed nominal frequency.
