Precise LED lamps dimming for stage technology
 Šojdr, Marek ; Šteffan, Pavel (referee) ; Levek, Vladimír (advisor)
This bachelor´s thesis discusses the problems of dimming of LED bulbs using DC voltage. It explains basic converters topologies and power factor correction options. Part of the thesis deals with the subharmonic oscillation and possibilities of its elimination. Describes the design of the circuitry of dimmer module for precise dimming of selected types of LED bulbs, revival and testing of the dimmer module. Part of the work is basic for realization of the dimmer (printed circuit board, list of components).
