Abstract

The research investigates the power losses and conversion efficiency in a DC-DC buck converter using three different types of MOSFETs: Silicon Carbide (SiC) MOSFET, Gallium Nitride (GaN) MOSFET, and Silicon CoolMOS. The analysis focuses on power losses (switching and conduction losses) and overall converter efficiency under varying load conditions. The first results are the total power losses of different MOSFETs with different current loads. The results show that a greater current load will produce greater power losses. The largest power losses occur in CoolMOS SPP11N60C3 at about 30.67 W, SiC MOSFET (C3M0075120D) at about 17.1 W, and Gallium Nitride (GaN GS66508B) at about 6.85 W in the current load 10 A. The second result is the total output power and efficiency of the buck converter which uses three different types of MOSFETs as switches with different loads (20Ω, 15Ω, 10Ω) respectively. So, of these three types of MOSFETs, the GaN MOS GS66508B has the smallest power losses and produces high output power, as well as keeping the efficiency above 99%.
