Abstract
Power conversion between alternating and direct current is a common application of Electrical Engineering in daily life, and most modern technology relies heavily on regulating voltage and current flow. This paper discusses the theoretical underpinnings, design, and assembly of a custom power converter built to convert the standard US outlet power of 120VAC to a 18.5V DC source and a 5V DC source: the goal of this device is to create a charger that can power a laptop and USB port at the same time with a single wall plug. The paper discusses the theoretical background of such a device, along with the practical aspects of its implementation. The design is then reviewed, and possible improvements noted.
