Facebook: / greatscottlab Twitter: / greatscottlab Support me for more videos: https://www.patreon.com/GreatScott?ty=h In this video we will be having a closer look at GaN FETs in order to find out whether they will improve power electronics products in the future. For that I got myself a commercial GaN power adapter which I will compare with a more traditional power adapter concerning their efficiency. Afterwards I will measure the resistance and switching speed of a proper GaN FET and finally use it in a buck converter circuit to demonstrate the difference to a normal MOSFET. Let's get started!
