Abstract
The paper describes selected properties of resonant cascades composed of magnetically coupled coils and designed for wireless electrical energy transfer. Methods for increasing a distance of wireless electrical energy transfer without having to re-calculate the system parameters were presented. The methods were illustrated by an example and verified experimentally: „wireless” method – 13 flat coils with outer diameter of 15 cm, transfer distance of 80 cm, operating frequency of 300 kHz, output power of 100 W, efficiency of 85,9%, „wire” method – 14 flat coils with outer diameter of 15 cm, total transfer distance of 80 cm, operating frequency of 300 kHz, output power of 100 W, efficiency of 83,5%.
