Abstract(s)
Recent developments, in the field of wireless charging, have led to increasing use of this technology
across different areas of research. The search for improvement in Soldier Combat Systems has seen major
investments in recent years, to find a standard architecture that can enhance military capabilities, such
as in power management systems. This work is part of the C4I program of the Portuguese army, having
had the primary objective of studying an alternative power supply option based on wireless technology,
capable of charging man-portable devices in military vehicles.
On this dissertation, it was conducted a study on the behavior of the components of a wireless
power transfer, focusing on different configurations and geometries of the charging coils, as well as the
optimization of key parameters in a wireless power module. For this, key operating principles and charging
methods were approached.
Using distance as a variable parameter, it was possible to study the variation in signal amplitude and
compare the performances of each coil, reaching promising conclusions on which coil geometry is best
suited in terms of shape, reach, and intensity of the generated magnetic field of the power transfer. Also,
the matching outcomes from the theoretical deductions and the experimental work done in a controlled
environment led to a strengthening of the obtained results.
After fabricating and testing prototype 3D structures for the coils, a proposal for a wireless charging
system was conceived. This proposal includes architecture, protocols, and its implementation taking into
account the characteristics of the charging environment.
