Abstract

High-voltage power systems are not well understood, motivating this research to examine performance differences of battery-based versus DC generator power sources on a hexacopter. With more high-performance Unmanned Aerial Vehicles (UAVs) on the market, the need to understand high-voltage power systems is increasing. A battery-based 12S LiPo system (15C and 20C) was compared with a 4000 W DC generator, and thrust, current, and power were measured with 24, 26.5, and 29-inch propellers. The battery-powered system produced more current and power and therefore more thrust at the same voltage than the DC generator system. The optimal configuration for the 12S20C battery was the 29-inch propeller, which produced 79.36 N of thrust. In contrast, the DC generator had to operate at a higher voltage (50.4 V) to achieve a comparable thrust of 79.17 N, which illustrates the differences between the two power sources. In high-voltage UAV applications, the power source selection guidelines are crucial.
