Abstract

Tema ovog završnog rada je bila karakterizacija silaznog prekidačkog naponskog regulatora s naglaskom na elektromagnetsku kompatibilnost. Prekidački naponski regulatori su efikasniji od linearnih, no pri radu emitiraju visoke elektromagnetske smetnje. Dozvoljene razine elektromagnetskih smetnji su propisane određenim normama i najčešće prekidački regulatori emitiraju elektromagnetske smetnje iznad dozvoljene razine. U ovom radu su isprojektirani filtri na ulazu i na izlazu koji su smanjili razinu smetnje. S time je uređaj elektromagnetno kompatibilan. U ovom radu regulator je analiziran pomoću LTspice simulacija i na samom kraju mjerenjem pomoću LISN-a.
Osim elektromagnetske kompatibilnosti, izvršena je karakterizacija prekidačkog naponskog regulatora. Odsimulirana je i izmjerena efikasnost regulatora, valovitost izlaznog napona, stabilnost, regulacija opterećenja i karakteristični valni oblici.

Abstract (english)

The subject of this work was characterization of switching voltage regulator with emphasis on electromagnetic compatibility. Switching voltage regulators are more efficient than linear, but they produce high electromagnetic disturbances. Permitted levels of electromagnetic disturbances are prescribed by certain norms and usually switching voltage regulators produce more disturbances than allowed. Because of that filters need to be added on input and output to decrease disturbances.In this work regulator was analyzed with LT spice simulation and finally measured using LISN.
Except EMC, characterization of switching voltage regulator was also done, efficiency of the regulator, output ripple voltage, line regulation, load regulation and characteristic waveforms were simulated and measured.
