Description/Abstract

With the increasing utilization of high power density batteries coupled with the technological advances in efficiency, smart power management is becoming an increasingly desirable asset. Most of the uses for this technology do not have a source of constant power instead the power supply and demand are usually in constant flux, requiring advanced power flow control. This control is desirable not only to system developers but also to consumers of electronic and electrical goods. The hybrid electric vehicle is one application for a power management system, where energy can be variably generated, stored or used depending on the state of the car. No pre-fabricated consumer microprocessor currently available can handle all the required tasks. This report intends to show that by using commercially available microprocessors as building blocks, an entire power management system can be built. The issue of DC power management and storage will be introduced with a review of background literature. A design for a bicycle light power management system using commercially available semiconductor devices will be described with models and practical measurements. A reasoned suggestion of further work is given as well as a review of budgeting and project timescale for this project.
