Low EMI three phase wireless charger for drone with 150 degree conduction mode of VSI

摘要

Wireless power transfer (WPT) technology enables convenient and automatic battery charging for drone. In spite of the great advantages, WPT system inevitably generates strong electromagnetic fields (EMFs), which causes interference on the nearby electrical devices. In order to reduce the effects of magnetic near-field noise and losses, a reduction in the harmonics of the source current is required. Therefore, we propose three phase wireless charging scheme with duty control of voltage source inverter (VSI) for a low electromagnetic interference (EMI) wireless charger.
