Toroidal-Shaped Coils for a Wireless Power Transfer System for an Unmanned Aerial Vehicle

Abstract

Modern and future warfare is shifting toward a space environment with manned and unmanned weapons. The need for unmanned aerial vehicles (UAVs) is increasing. The modern military weapons system is based on the use of communication, sensors, and navigation equipment to accomplish a given task, even in hard-to-reach areas UAVs include all types of equipment, including drones, satellites, and missiles, among others. However, as UAVs become more advanced, their maintenance and repair also require a higher level of scientific technology. Conventional UAVs depend on fuel cells with high-energy density for operations. The fuel cell will not stop burning once it has been ignited UAVs with fuel cells have a 10-year life span. They can avoid misfire and accidents by conducting periodic safety maintenance of the charging and power supply systems. The current UAV power supply maintenance method is shown in Fig. However, this maintenance method has three problems. First, a large number of direct cables must be connected and then disassembled each time to supply the power. This condition increases the possibility that maintenance time is expanded or that maintenance efficiency is
