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...
Wireless power transfer (WPT) technology is becoming increasingly popular for wireless charging of mobile phones and electrical vehicles. Because high power energy is transferred via air, however, the problem of electromagnetic radiated emission from WPT systems is expected to be serious. In this paper, an electromagnetic interface (EMI) and radiation from WPT systems are discussed. Three example...
