About this document
Understanding THDi in Luminaires and Inverters by tubolyt is a document available to read on EtoBox.
The document outlines the IEC 61000-3-2 standard for luminaires, categorizing them based on wattage and specifying limits for harmonic currents. It discusses the performance differences between cheap and quality ballasts, as well as the impact of dimmable luminaires on THDi values. Additionally, it covers the operation of frequency converters in controlling motor speed and their associated harmonic current emissions, emphasizing the need for appropriate filters to reduce these harmonics.
