Sony Create wireless power transfer system for HDTV.
With the growth in networked products, the quantity of cables used to connect these products has increased more. While data cables are being replaced with wireless communication systems such as Wi – Fi, the demand for wireless power transfer systems is also continuing to grow.. Sony will proceed with its efforts to develop technologies that applicable customer needs for the wireless transfer of power across a wide rang of products, distances and energy levels. It would be truly amazing to see a television one day that has wireless HD, power, and Internet capabilities
Sony has announced the development of a highly efficient wireless power transfer system that eliminates the use of power cables from electronic products such as television sets. Using this system, up to 60 Watts of electrical energy can be transferred over a distance of 50cm ( at an efficiency of approximately 80 %, approximately 60 % including rectifier ). This new wireless power transfer system incorporates a form of contactless electrical energy transmission technology based on magnetic resonance. With magnetic resonance, electromagnetic energy is only transferred to recipient devices that share the identical resonant frequencies as the energy source, so energy transfer efficiency is maintained, even when misalignment occurs. Furthermore, even if there are metal objects located between the transmitter and receiver, no heat induction occurs
Sony has and drawn on its senescence of skill developing high radio frequency ( RF ) technologies for use hold wireless communications and broadcast products to shape a new rectifier that realizes both high efficiency and speed. The new wireless power transfer system combines these technologies to transfer efficiency of 60 %, even when a rectifier is included. Sony has developed passive extender units that are set to the same frequencies as the transmission and recipient devices, enabling the transfer distance to be extended from 50cm degradation free in transfer efficiency.
Hope to see it on the market soon.
