A comparison of receiver topologies for Digital Load-Side Transmission in general LED lighting

摘要: Digital Load-Side Transmission (DLT) is a two-wire bound power line communication methodology that has been specifically developed for general lighting applications and transmits data over mains. This paper proposes three DLT receiver concepts compares them to one other regarding robustness, complexity consumption. All of these detectors have realized tested in hardware. To evaluate robustness terms utility grid variations, 24-hour long term measurements taken each concept, when connected 50 Hz A telegram error rate (TER) measured all setups, while the consumption implemented receivers determined by Simulation Program with Integrated Circuit Emphasis (SPICE) simulations. fully digital approach an active analog bandpass based structure seem be most promising solutions as they feature comparable TERs 44 80 parts per million (ppm), respectively. presented topologies can monolithically integrated on chip facilitate development highly integrated, intelligent LED drivers.
