A new measure for wireless power transfer to support highly efficient links

2015-10-09 16:39:29| Wireless - Topix.net

For wireless power transfer to deliver on its promises, such as contactless powering, electric vehicles, and energy harvesting, it needs to achive better levels of efficiency To construct a wireless power-transfer system, a "wireless transfer coupler" is necessary to deliver the energy from a high-frequency power source to a load, with no physical contact. In the past, "coupling coefficient k" was used as an index of wireless-power-transfer efficiency.
