Study unfolds Universal Multi-Standard Wireless Charger

Engineers are the backbone of the world. The new invention means a new technology been emerged. The greater thinking and finer approach makes an engineer different and standalone in the field. Engineers have now also come up with the invention of a new technology by firm planning and decisions. A new technology is to develop a wireless charger that will be compatible with different consumer electronics from different brands.

A dual frequency wireless charging platform has been developed by the team from University of California-San Diego that can charge smartphones, smart watches, laptops and tablets at the same time, regardless of which wireless standard, or frequency, each device supports. Patrick Mercier, professor at UC San Diego who led the study, explained, "To our knowledge, this is the only multi-standard wireless power transmitter that's been shown to operate simultaneously at two different frequencies with high efficiency".

There are three wireless standards in the market. Wireless charger needs to be either the Qi, Powermat or Rezence standard supportive. Pestering the current incompatibility of the wireless charger, the new Universal wireless charger cum single charging device supports multiple standards. It needs to operate across these very different frequencies as, Qi and Powermat operate at around 200 kHz while Rezence operates at 6.78 MHz.

"To help avoid such a situation, we developed a wireless technology that is universal and supports all of these standards so it won't matter which standard your device supports", Mercier added. Clearing the words, to address the problem, Mercier and his team built a charging platform capable of simultaneously operating across the frequencies supported by all three wireless power standards. The paper too was published in the journal IEEE Transactions on Power Electronics, with the notable note carrying the information that, the researchers have filed the patents and are looking for commercial partners to help bring the universal wireless charger into the market.
