Power supply for acquisition and communication subsystem of a current transformer
Beran, Tomáš ; Král, Jan (referee) ; Kubíček, Michal (advisor)
This bachelor thesis is focused on designing a power supply for measuring part and communication part of a device, which is supposed to analyze current waveforms on high voltage lines. The power supply consists of a current transformer, control electronics, and accumulation elements. The thesis analyzes the current waveforms on high voltage lines to get an overview of input data so that the right current transformer can be chosen. A working principle of these transformers is described, as well as the options for accumulation elements. Power supply requirements for the power supply are determined as well. The next part of the thesis summarises this theoretical knowledge and applies it to the schematic design. This is followed by a description of the schematic with an included description of function blocks. Additional adjustments that would improve the power supply's properties might be mentioned. This will be followed by designing a PCB layout. The final part includes the manufacturing process and determination of parameters like power, efficiency, etc. In the manufacturing process, the PCB will be printed, soldered, and evaluated on an electrical test. The electrical test inspects the functionality of the designed power supply by simulating real-life scenarios of high voltage lines. At last, an impact of the power supply on the measuring system will be analyzed.
