Abstract
Power quality improvement of power electronics systems in many applications such as Adjustable Speed Drive (ASD) is vital due to high penetration of grid connected converters in distribution networks. However, due to the switching nature of the power electronics devices, ASDs have been witnessed as a major source of current harmonics in distribution networks. Due to the cost effectiveness, simplicity, and reliability, still conventional bridge diode rectifier is utilised in many three-phase systems. Thus, in this paper, a three-phase bridge rectifier with harmonic mitigation function is proposed using an electronic inductor. The proposed method can mitigate current harmonics caused by other conventional rectifiers connected at the same Point of Common Coupling (PCC). Based on the proposed harmonic reduction technique, a combination of three-phase rectifiers can comply low order harmonic emission according to IEC 61000-3-12 standard. Simulation results have been carried out to validate the proposed method.
