Because wireless power transfer (WPT) systems used in automotive vehicles are likely to cause electromagnetic interference (EMI) with sensors, antennas, and controllers, the magnetic near-field spectrum from a WPT system has to be investigated and controlled properly. In this paper, we propose a selective harmonic elimination (SHE) method of the radiation noise from an automotive WPT system to reduce...
Wireless power transfer (WPT) charging technology using magnetic field can transfer power to battery for drone without any electrical contact. It can be one of the safe and convenient battery charging methods. In spite of the great advantages, WPT system generates strong electromagnetic fields (EMFs), which causes interference on the electrical devices such as DGPS, speed controller, Bluetooth data...
For wireless charging of electric vehicle (EV) batteries, high-frequency magnetic fields are generated from magnetically coupled coils. The large air-gap between two coils may cause high leakage of magnetic fields and it may also lower the power transfer efficiency (PTE). For the first time, in this paper, we propose a new set of coil design formulas for high-efficiency and low harmonic currents and...
