Abstract:
This thesis focuses on optimization and increasing the efficiency of high-power DC/DC switching converters with transformer (switching power supplies). The work focuses mainly on using converters with flyback topology for high power, even though it is a common belief that this type of converter is not suitable for high power. This topology was selected because of potentially better achievable parameters, especially the efficiency, in comparison to a commonly used forward converter – in a flyback converter, losses are produced only in one magnetic component (transformer) in contrast to two comp

Abstract:
The goal of this thesis is to improve efficiency of an induction motor. In the first part, the working principle is described. The next part deals with the origin of losses and possible solutions to decreasing losses without impacting the production possibles. The third part of the thesis is focused on the calculation of parameters of a small serial production motor. In the fourth part, these parameters are verified using the analytical tool RMxprt which is included in Ansys Maxwell. The fifth chapter deals with the optimization using Matlab genetic algorithm. In the final chapter, the design
