Abstract A survey of different methods for lighting control has been accomplished. A description of many types of electric lamps is given. A study of higher harmonics and their values at different values of(~Jare obtained. The main achievement gained in the course of work is the experimental results. These present the actual relationships between voltage and current of the load and the firing angle of thyristor controlled li~1ting equipment. Also the research includes comparison between traditional methods and converter circuits of lightinG control |
