Reduction Radiated EMI from the Power Distribution System of an Unmanned Aerial Vehicle

The paper presents the procedure for minimizing electromagnetic radiation from the power distribution system of an unmanned aerial vehicle. The procedure consists of a heuristic algorithm that routes current paths in such a way that the area of current loops is minimized, a genetic algorithm for determining the sequence of conductors routing and criterion of electromagnetic radiation. The results of applying the procedure to two problems are also presented. The first problem is to minimize electromagnetic radiation from the power supply, which is a component of the power distribution system of the unmanned aerial vehicle. The second problem is to minimize electromagnetic radiation from all current loops formed by direct and return conductors of the unmanned aerial vehicle's power distribution system located in one of its compartments.
