Návrh a realizace DC/DC měniče pro napájení řídicí jednotky BLDC/PMSM motoru

Abstract

This bachelor's thesis focuses on the design and implementation of a switched DC/DC converter with Flyback topology, intended for powering the control unit of a brushless synchronous motor with permanent magnets (PMSM/BLDC). The primary goal is to create an efficient and reliable converter capable of drawing energy from a lithium battery or another DC source with a large voltage range from 20 V up to 80 V, and providing stable power for the inverter gate drivers and logical parts of the control unit. The work includes research on Flyback topology, requirements for implementation, design of the Flyback transformer and components for realization, simulation in OrCAD software, and experimental verification of the implemented converter design.
