Analysis of Harmonic Suppression and Power Factor Correction Technology in Lighting Power Circuit
ZHANG Ce
Abstract：With the continuous renewal of lighting technology,the phenomenon of harmonics in the strong current circuit and the low power factor value is gradually aggravated.This study focuses on the discussion of harmonic suppression technology and power factor correction technology,explores the design methods of passive,active and mixed filters in detail,and analyzes various channels to improve the power factor value from two dimensions of passive compensation and active compensation strategies.Through the measured analysis of two typical projects,including the lighting system of a large commercial complex and the intelligent lighting project of a university teaching building,the application effect of the comprehensive technical scheme is verified.Two innovative directions are proposed:the hybrid filter optimization technology based on adaptive control and the multi-mode power factor correction topology optimization.After examining typical lighting engineering projects,a comprehensive improvement plan is proposed to optimize the power quality and operation level of the lighting system as a whole.
