Abstract
The emergence of GaN devices have brought new challenges within power electronics especially consumer electronics since the voltage rating has not become as high as silicon carbide. This new emergence resulted in an increase in switching frequency capability of power electronics circuits and may be used to increase the efficiency of current topologies, decrease the profile, and cost of the total circuit. Since most important and expensive part of each SMPS is its inductor, the increase in switching frequency will result in a significant decrease in passive component size and potentially the total price of the circuit. Nowadays most people carry laptops, cellphones and in general a lot of handheld devices and all of them need charging. Previously, every single device has its own specific charger and as a result, you had to bring multiple cords and chargers to make sure you do not run out of battery. With the development of USB-C, the era of multiple chargers has ended. Instead, a single cable and a single high capacity charger or power bank is sufficient to carry through each day without running out of battery. This thesis will investigate a 60watt USB-C charger with power delivery to fast charge every USB-C compatible device. The objective is to modify an existing topology which has the least number of components and make it as efficient, small, and cost effective as possible.
