Abstract

This bahelor´s thesis deals with the analysis of selected topologies of half-wave and full-wave rectifiers using operational amplifiers. The topologie were selected with regard to the design of a labratory setup, and their properties were verified through simulations in the OrCAD PSpice environment and experimental measurements.

The labratory setup was implemented in two variants differing in the active components used, which enabled not only a comparison of individual topologies but also a clear demonstration of the influence of the dynamic parameters of the operationl amplifier and the diode on the resulting rectifier behavior.

The measured results were compared with simulations and used to develop a labratory measurement guide. The proposed setup is suitable for labratory education and enables a clear demonstration of the properties of operational rectifiers.
