Spínaný napájecí zdroj pro světelný LED panel

Abstract

This bachelor’s thesis focuses on the complex design and implementation of a switching power supply for LED panels, with an emphasis on high operational reliability and long-term durability. The theoretical section of the thesis compares linear and switching power supplies and defines key requirements for modern systems in the field of power supply electronics. A review of integrated circuits is also conducted. Based on this review, a switching power supply circuit was selected whose parameters best meet the need to create a device capable of handling heavy loads without the risk of failure. In the practical section, a project using this circuit is assembled, and the final chapter presents the results of measurements on the power supply, including the spectrum of emitted signals. The project includes documentation for the implementation of the power supply, specifically a printed circuit board design and a list of components used.
