Abstract:

A need exists within the Nett Warrior program to wirelessly charge soldier mounted electronic devices. Currently soldiers either carry extra batteries or dismount their electronics and deal with the logistics of a variety of cords to charge their electronic devices. Current wireless inductive chargers suffer from range limitations, and require complex control electronics to properly couple the transmitter and receiver devices. Busek has developed an autonomously adaptable wireless power charging circuit. Its design allows the fundamental oscillating frequency to be almost completely determined by the load. This means what was previously accomplished in active control software is realized by the nature of the circuit itself. The advantage of load determined resonance is the inherent ability for the circuit to deliver maximum power without actively tuning the operating frequency for maximum coupling. In Phase I the self-tuning wireless charging circuit will be developed. This circuit will be analyzed and adapted for use as a transmitter. Its performance will be evaluated and analyzed when coupled to single and multiple loads. The safety and performance of the circuitry via 3-D electromagnetic simulations will be evaluated. The goal is to ensure electric and magnetic field strengths remain within safe exposure limits while providing suitable efficiency.
