Analiza właściwości rezonansowych kaskad cewek ze względu na zwiększanie odległości przesyłu

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%.
