Wireless power transfer (WPT) is expected to spread around the world. WPT has two types, one is magnetic induction and another is magnetic resonant coupling (MRC). In magnetic induction, the amount of received power is determined by the transfer distance and the amount of magnetic flux through receiving coil. Therefore in transferring power to multiple receivers at each fixed transfer distance, power...
Wireless power transfer is a popular research topic in recent years. Allowed frequencies for wireless power transfer (WPT) are limited by the industrial, scientific, and medical (ISM) radio bands and each country's law. Different applications of wireless power transfer need to use different frequency bands. A single transmitter coil which can adapt to multiple frequency bands is needed to reduce the...
Wireless power transfer is a popular research subject in recent years. Available frequency for wireless power transfer (WPT) is limited by the industrial, scientific, and medical (ISM) radio bands in MHz band and some laws. Depending on the application of wireless power transfer, different frequency bands are used. A single transmitter coil which can adapt to multiple frequency bands is needed for...
