Abstract

This paper presents results of experimental and analytical evaluation of power-dependent harmonic emission of three common types of modern low voltage (LV) power electronic (PE) devices. After a detailed analysis of comprehensive test results, based on both existing and new waveform distortion indices, the development of component-based models of PE devices is discussed. The paper demonstrates the importance of including PE devices’ controls for accurate modelling of their characteristics over the entire range of operating powers. Most of the analysed PE devices exhibit strong power-dependent changes of characteristics, additionally influenced by supply voltage conditions, which are important for the analysis of both existing networks and future “smart grids”.
