Abstract

© The Institution of Engineering and Technology 2014. It is not a secret that the problem of harmonics and switching frequency can have a dreadful impact on switching power converters. To counter this problem, a variety of methods have been developed over the years. In this study, a novel method for controlling/eliminating harmonics in switching converters, based on real-time harmonic control, is suggested. The proposed method allows a complete control of the number of eliminated harmonics, as well as the fundamental. The method adopts a modulation strategy using a modified sine carrier. To determine the inverter's optimal switching angles, the well-established particle swarm optimisation algorithm is used. In order to assess the performance of the proposed approach, simulations are carried out. The validity of the method is demonstrated using the digital signal processor based dSPACE environment. The experimental results are very satisfactory and clearly prove the validity of the proposed approach.
