Analytical Study and Reduction of Harmonics Issued from LED Lamps in Lighting System



Harmonics are unavoidably generated in any non-linear electrical/electronic systems, and cause severe problems in terms of performance and operation. This paper focuses on analytical study and reduction of harmonics originated from LED lamps usually functioning with high switching-frequency driver. Since the driver is a switching device, it will be thus a direct harmonic and/or electromagnetic interference (EMI) source of the system. In order to suppress or reduce produced harmonics, a low-pass harmonic filtering technique is proposed and applied. The experimental results can reveal harmonic reduction effectiveness by comparing with a lighting standard, which is herein IEC 1000-3-2 (or EN 61000-3-2); this confirms finally the Electromagnetic Compatibility (EMC) of the system.
