Abstract

This study focuses on DALI lighting control interface and DALI cabling. DALI interface circuit will be designed and presented. DALI wiring is typically made by using a standard PVC (polyvinyl chloride) insulated electrical cable. Electrical characteristics of such a cable will be defined to fully understand the frequency dependent behaviour of the cable. The self-inductance, mutual inductance and resistance of the cable will be resolved by using a numerical method called volume fillet. PVC material data, like the relative permeability and the loss tangent, will be resolved by using the results of material science studies. A lumped model presentation for the cable will be created. Time dependent simulations for the interface and the cable will be executed using Spice. The usability of the lumped model will be issued. The lumped model can be extended to a distributed model. Neither of these models can handle the frequency dependence on the electrical characteristics. There are some options how to improve the model.
