Harmonic Analysis of LED Lighting and Its Influence on Power Distribution Design
Abstract: LED lighting has been greatly promoted due to its high energy efficiency. However, the driving power characteristics of LED lighting make a large number of high-order harmonics in the lighting distribution line, and the generation of harmonics makes the design and power distribution of the lighting system more complicated. This paper combines the lighting related standard specifications, from the LED lighting harmonic generation principle, and analyzes the influence of harmonics on the lighting system design, and puts forward some key points of the LED lighting system power distribution design.
Keywords: LED lighting; harmonics; power distribution design; drive power;
