Abstract: | At Tomas Bata University a Ph.D. project focused on Autonomous monitoring system is being solved, dealing with an independent operation of a small airship inside an enclosed hall. It includes a design of the controlling unit, including the power delivery. The power source must be equipped with three voltage converters (SMPS) capable of delivering standardized voltages to the particular circuits of the controlling unit. As the energy source, two-cell Li-Pol accumulator is employed. In this paper an approach to the design of the synchronized voltage converters set is described, considering the following requirements: preserving a long life of the Li-Pol accumulator, high supply voltage conversion efficiency, overcurrent protection, easy hibernation and the last but not least, low disturbing electromagnetic radiation. The main part is dedicated to the optimized synchronization of the particular SMPSs in order the minimum pulse component of the supply current was achieved. |
