Experimental Investigation of a Scalable Dimensionless Model of an AC Circuit with a Nonlinear Rectifier Load

Year: 2025

Type: article

Abstract: This paper develops a compact and scalable mathematical model of an AC circuit with an uncontrolled diode bridge rectifier, formulated using dimensionless variables. The model captures the joint influence of supply inductance, resistance, and load parameters on current waveform distortion, harmonic content, and reactive power exchange, which are often simplified or addressed separately in existing studies. Experimental validation confirms the applicability of the model over a wide range of operating conditions and grid strengths. The results provide quantitative characteristics that support the interpretation of power quality measurements and the assessment of how nonlinear loads interact with non-stiff supply sources. The proposed formulation offers an efficient analytical tool for harmonic analysis in distribution networks, particularly where a balance between modelling accuracy and computational effort is required.
