Fujitsu Laboratories has successfully developed a compact high-efficiency wireless recharging technology which is based on magnetic resonance capable of simultaneous recharging of several types of portable electronic devices. Along with its compact design and high efficient power transmitter and receiver, the new technology offers the capability of designing charging systems in 1/150th the time currently required. With this dramatic short development time, the new technology paves the way for integrating compact wireless charging functions within mobile phones and allows simultaneous charging of several mobile devices irrespective to their position to charger. The new technology features a magnetic field analysis simulator capable of analyzing the coil model, plus a specialized circuit simulator which analyzes the resonance conditions, including the capacitor model, that allows quick and accurate design of wireless charging systems for multiple transmitters and receivers at once using a variety of coil sizes. Furthermore, the design of the wireless charging systems can be automated to precisely match the desired resonance requirements, all based on an assessment function that maximizes the charging efficiency.
