A wireless power transmitting system for a traveling mobility scooter based on magnetic resonance has been developed. In the system, we have prepared 2 kinds of loop: ordinary square loop and fractal loop. In this paper, we demonstrate that the fractal loop can keep high efficiency in spite of lateral positioning deviation with a fixed matching circuit.
A wireless power transmitting system for a traveling mobility scooter based on magnetic resonance has been developed. In this paper, an overview of the system will be presented. Large square coils are set up on the road surface where a mobility scooter with a small coil and no battery is traveling. The power source is a Class E amplifier operating at 13.56MHz with an output power of 150W. Power is...
