Wireless power transfer systems exist in smartphones, electric toothbrushes, and IoT sensors. They use electromagnetic fields ...

Wireless power transfer (WPT) systems transmit electrical energy from a power source to a load without physical connectors or ...

A nonlinear parity–time-symmetric circuit is used to enable robust wireless power transfer to a moving device over a distance of one metre without the need for tuning. A robust, efficient ...

In its infancy, the wireless power transfer system industry was forecast to be around 1 trillion yen; it has actually not yet achieved a scale of 200 billion yen.

Wireless power transfer is based on the Wireless Power Consortium’s WPC 1.1 Standard (July 2012) that facilitates cross-compatibility of compliant transmitters and receivers.

If resonant wireless power transfer (WPT) systems are to fulfill their promise for charging electric vehicles and other high-power applications, there is an engineering issue that must first be ...

Scientists have successfully developed a new power controller system for wireless power transfer. The developed system will effectively reduce the amount of circuit components in wireless power ...

The efficiency of wireless charging systems is limited by power loss occurring due to frequency changes in the resonant circuits that enable power transfer. These necessary modulations reduce ...

The system is designed to provide reliable, high-efficiency power transfer amid the extreme conditions of the lunar surface, including a night that lasts 14 Earth days.
