Fázové spínání světel řízené mikroprocesorem

Abstract

The aim of my thesis was to design and implement a phase control device that will adjust the brightness of eight lights. The work included the selection of the choice of control, analysis of communication protocol, selection of active and passive components and the implementation of PIC18F452 microprocessor software. Furthermore, it was necessary to design critical circuits, which are used for power control of the load phases and are necessary for performance of the equipment. It is the power supply, zero-crossing detection circuit, the transmitter of the differential signal to TTL levels and a power stage. The final stage involved designing the PCB and manufacturing of a functional prototype, for which the technical documentation was then written.
