Abstract

This thesis aims to outline the problems of design of switching power supplies with pulse transformer. This work can become a recipe for the construction of similar resources in everyday engineering practice and from the theoretical to the practical. Solves the typical technical difficulties both in the form of the choice of suitable components, such as a choice of topological solutions. The first part discusses the situation on the part of legislative requirements that are given by valid government standards, which are based on European standards. It describes the basic procedure for designing inverters including design input filter, output filter, semiconductor components, basic control circuits and feedback. There is a design of a cooling of individual elements, including a quantification of values and on their basis the selected suitable cooling profile. The work also includes the printed circuit board design and a brief presentation of the results of the measured values.
