Switching power supply unit for an autonomous monitoring system

Abstract

There is a project of Autonomous monitoring system being solved at Tomas Bata University in Zlin. Within the framework of this project a small airship driven by ultrasonic detectors is developed. This airship shall be capable of independent operation in an enclosed hall, bearing a camera or another monitoring system. There are several voltages needed to power the circuits of the airship. To ensure their feeding from a Li-Pol battery, a small and lightweight power supply has been designed. In this article, aspects of designing such power supply unit are analysed.
