Abstract

Sklopke temeljene na galijevom nitridu imaju mnoge prednosti u odnosu na sklopke temeljene na siliciju ili silicij karbidu. GaN sklopke mogu raditi na visokim ulaznim naponima i na visokim temperaturama. Svoju primjenu nalaze u sustavima visoke snage poput električnih vozila. Ove sklopke imaju nizak naboj upravljačke elektrode i rade na visokim frekvencijama, ali je njihovo upravljanje komplicirano. U ovom radu opisan je polumosni pretvornik s GaN sklopkama. Pretvornik je dizajniran u programu Altium Nexus, a potom je proizveden. Sklopke mogu raditi s ulaznim naponima do 1200 V što znači da su provedeni testovi visoko-naponski.

Abstract (english)

Gallium nitride-based switches have many advantages over silicon or silicon carbide based switches. GaN switches can be operated at higher input voltages and at higher temperatures. They are often used in high-power systems such as electric vehicles. These switches have a low gate charge and can operate at high frequencies, but this makes them difficult to operate. This thesis describes a half-bridge converter with GaN switches. The converter is designed in Altium Nexus and then produced. The switches can operate with input voltages of up to 1200 V, which means that all tests performed were high-voltage tests.
