Jednofázový usměrňovač řízený mikroprocesorem

Abstract

The introduction of the bachelor thesis is focused on the problems of phase control of the controlled rectifiers in the analog control area with both passive and active objects for explanation of element principles for thyristors lauching. There is described the way of rectifier number control by microprocessor and its advantage in comparison with conventional systems. The main point of the bachelor thesis is the project and the realization of number control unit for single-phase thyristor rectifier that can be used for laboratory purpose. There is also the experimental measurement with the connected thyristor rectifier to test out the possibility of the controlling and to detect weak points if there are any.
