Abstract :
This paper presents a novel transformer topology to feed power converters under voltage imbalance supply based upon a novel approach of the special transformer ADZ, whose main contribution is noncharacteristic harmonics mitigation. Additionally, the impact of voltage unbalance factor (VUF) in the power converter harmonic generation is analyzed by addressing VUF, harmonic order and its magnitude, as well as positive voltage sequence, harmonic order and its magnitude. This analysis also contributes to show how powerful the proposed topology is, as well as its technical feasibility.
