Electrical Engineering
The Electric Bicycle System is a systems project that incorporates three different ways of charging a lithium-ion battery: the 120VAC wall outlet, regenerative braking, and solar power; which is used to power an electric hub motor running a bicycle. The purpose of the project is to show that it is possible and relatively simple, to build an electric bicycle by oneself. This project can be broken down into five separate categories: the lithium-ion battery, the DC-DC boost converter, the solar panel, the motor, and the motor controller. Each of these will be built upon and improved further by future students, …

Electrical Engineering
The automated Magnetic Design Web Application, available at http://www.magneticdesign.org, generates the full design process of a power transformer, gapped inductor and toroidal inductor given design specifications provided by the user. Calculations are accomplished using Area Product, Ap, or Core Geometry, Kg, procedures. All design processes mirror the format used in Dr. Taufik’s Introduction to Magnetic Design lecture-notes. An administrative backend is provided where instructors can add or modify core design values to expand the array of materials used. The project aims to aid student understanding of magnetic design and course concepts while allowing instructors to broaden the scope of material …
