Abstract
The beginning of the XXI century brought a further significant development in
the use of autonomous electrical and electronic equipment. The low consumed
power equipment is widely used: laptops, mobile phones, PDA, wireless
headphones, implants, razors, toothbrushes etc. The higher power consumption
equipment is also starting to work wirelessly, e.g. the intelligent machining
complexes, robots, the forklift trucks, and electric or hybrid cars. The
desired autonomy and transportability of the equipment requires autonomous
energy sources. Until now, almost without exception, the autonomy is
guaranteed by electrochemical power with its main problem: to charge, replace
and dispose batteries. Engineering world is seeking a non-conventional,
wireless transfer of energy, both for charging batteries and directly
supplying the equipment. The electromagnetic field is the usual carrier for
telecommunicated information. Here an example is shown of electromagnetic
transfer of energy, avoiding even the use of ferromagnetic cores.
