Magnetic Coupler Optimization for Inductive Power Transfer System of Unmanned Aerial Vehicles

Unmanned aerial vehicles (UAVs) have been widely used in military and civilian applications. However, the insufficient cruising range restricts the development of UAVs due to the limitation of their battery. Inductive power transfer (IPT) is an effective way to charge the battery and solve this prob...

Magnetic coupler is a key component of the IPT system, which greatly affects the power transfer and efficiency of the IPT.
