Possibilities Of Wireless Charging For Multipurpose Electronic Systems
MetadataShow full item record
This article describes possibilities of wireless charging (WC). One of the main application fields lies within small-size electronics and currently also the recharge electric vehicles (EV). Wireless Charging Station (WCS) is based on inductive power transmission (IPT) of electrical energy. The station is divided into a docking station and a charger. It includes invertor operating up to 108 kHz, a circular spiral coil on the receiving and transmitting side, rectifier with step-down converter and controllers. Wireless modules communicate in the ISM band with GFSK modulation, and are used for voltage and current monitoring in the charger, which can determine the insufficient position of the coils. This is also a way to enable accurate landing for unmanned aerial vehicles (UAV) instead of landing with camera and quick response (QR) code detection. Nevertheless, for precise guidance UAV towards station is necessary the global position system (GPS). The electromagnetic interference (EMI) in the shielded chamber was measured to give the idea about electromagnetic radiation.
KeywordsWC - wireless charging, IPT - inductive power transmission, EMI – electromagnetic interference, WPT- wireless power transfer
