Kompaktní elektronická nadproudové ochrana

Abstract

This bachelor's thesis discusses the current methods of overcurrent protection and analyses the possibilities of sensing the current of the protected circuit in an electronically controlled overcurrent protections. In the practical part, in consultation with the thesis supervisor, the purpose is to design and implement a power electronic overcurrent protection system powered by an independent battery supply. Once the design is complete, simulations are performed using the PSpice simulation environment to verify device functionality. Finally, after completion of the PCB design, the components are assembled, initialized and tested by using a laboratory power source. The measurement results are documented in the form of oscilloscope images.
