摘要

This paper mainly focuses on the combination of magnetic levitation height adjustment and wireless charging. The magnetic levitation height adjustment is provided by adding both an electromagnetic levitation coil and a ready-made magnetic levitation platform. This design changes the magnetic field strength of the electromagnetic levitation coil with a Pulse-Width-Modulation (PWM) signal in order to adjust the magnetic levitation height. The wireless charging uses a wireless charging coil with an adjustable resonant frequency and coordinates with the height of the magnetic levitation to find a better wireless charging efficiency.
