Abstract

This paper discusses the power management of an electronic light- and tachometer system for bicycles. The system uses a conventional hub dynamo as energy source. An accumulator battery is charged via a microprocessor controlled AC-DC converter. We develop a circuit model of the hub dynamo. In order to maximize the output power load matching is performed. A simulation analysis as well as measuring results show that the presented solution is more efficient than classical power supply arrangements and offers the basis for new features. We develop a suitable AC-DC converter topology and show its practical performance
