  • Publication number: 20190182917
    Abstract: Low cost and low power LED lamps exhibit current harmonic contents due to their nonlinear characteristics. A large scale lighting network requires tens to hundreds LED lamp installations, the resultant harmonic currents pollute the grid seriously. Furthermore, light intensity fluctuations are becoming a concern nowadays to many users, as a safety and a health problems. This phenomenon is mainly caused by heavy loads as they lead to voltage fluctuations and deteriorating in PQ and hence visual flickering in LED lamps. A single phase transformer-less unified power quality conditioner (UPQC) topology is provided with its controls to mitigate all PQ problems in a network.
