Abstract:

Modern LED lighting offers significant advantages over incandescent lighting regarding efficiency and over CFL lighting, both regarding the efficiency and including the ability to regulate luminous flux. However, LED lamps are nonlinear loads that inject higher-order current harmonics into the power grid. In this paper, the impact of switching to single-phase dimmers and DC-controlled drivers on power quality will be analysed.

Keywords:

LED, dimmer, harmonics, power quality, THDI.
