Design and prototypng of a new switched-mode power supply for an electrical vehicle

In this study, we explain several well-known topologies (the basic elementary building blocks) that are widely used to design and implement linear and switching power supply. For each topology there are common and unique characteristics, so an experienced designer will choose the most suitable structure for the intended application. In general, the choice maybe difficult, so it ought to spend a few times to create an essential understanding of the properties, since the right initial choice will dodge sitting around idly on a structure that will not be the most excellent for the application. In this work, some topologies used in switch mode power supply SMPS are described in detail, and each topology is described with the specified mathematical equations for each of its components, and the output of these topologies is shown. A comparison of isolated and non-isolated topology types and the characterization of voltages and currents in each part of the design are presented. In the end, the simulation was carried out using the Python language, and the practical results of the studied designs were presented, and they matched with the theoretical study
