Simulace usměrňovačů a DC/DC měničů v programu OrCAD PSpice

Abstract

The bachelor thesis deals with simulation of rectifiers and DC/DC converters in OrCAD PSpice. In theoretic part, basic classification of rectifiers and DC/DC converters is carried out and basic functions of one-pulse, two-pulse, three-pulse and six-pulse rectifiers with resistor load are explained. Other types of loads are explained for single-phase bridge rectifier. Functions of one-quadrant, two-quadrant and four-quadrant DC/DC converters are described as well. OrCAD is described at the end of theoretic part. In practical part, simulation models of basic rectifiers and DC/DC converters are created. Function of rectifiers is examined for various types of load and firing angles and function of DC/DC converters for various duty cycles and results are compared with theoretic hypothesis.
