Wireless Charging And Data Communication Of An Unmanned Aerial Vehicle, Shang-Kai Wei

All ETDs from UAB

Wireless charging system in current market usually uses Class D oscillator in the transceiver side, however, this design is highly power consumption and low transfer efficiency. In this report, Class E oscillator is used to decrease the power consumption. Class E oscillator is perfectly zero voltage switching and high transfer efficiency. To increase the wireless transfer efficiency, spiral PCB inductor is also used as the wireless charging pad. Spiral PCB inductor usually uses for RF circuit with high accurately, moreover, the inductance and Q-factor is higher than current wireless charging coil with Litz or magnetic wire. In the receiver side, …
