Novel technology decrease laptop adapters to 1/4th

While laptops continue to decrease in size & weight, "power bricks" that charge them remain overpowering & large. But under the present circumstances, MIT spinout FINsix have design an adapter that's approximately 1/4th the size & one-sixth the weight of a conventional brick, & has maximum working productivity with minimum waste.
Co-founded by four MIT alumni—Vanessa Green MNG '08, MBA '11; Anthony Sagneri SM '07, PhD '12; George Hwang PhD '10; & Justin Burkhart SM '10—FINsix has developed the world's smallest laptop adapter, named as the Dart. Around about 2 1
/2 in cubic in size & weighing approximately 2 ounces, the adapter is slightly bigger than an ordinary plug.
The Dart runs on novel very-high frequency (VHF) power conversion tech, co-invented Sagneri that bring and hand over energy more often & in smaller chunks than normal adapters, being wasting less energy. It will do that by adapter's switching frequency—which transfers energy from the adapter to the battery—run one thousand times faster.
"If you can increse that frequenci, u can reduce the amount of energy that you have to store temporarily in the inductors & capacitors—which make up the bulk size & weight of power bricks—during the conversion process, & that yields reduced size," Sagneri explains.
The 65-watt Dart can power majority of laptops, smartphones, & tablets. By Novmbr, FINsix target to handover its 1st shipment of nearly 4,500 Darts to customers.
Although Dart is FINsix's first product, Green said that the company aiming to brought VHF technology to wide range of applications. This could decrease the AC & DC power converters for products e.g. LED lights, laptops, electric bikes, flat-screen TVs, & air conditioners, while decreasing the cost of making.
The technology can also help to decrease energy consumption with more appearing power conversion.

Decreasing the bucket

Under the instruction of David Perreault, which is the professor of electrical engineering in MIT, Sagneri helped design a novel circuit that executes power conversion at very high frequency30 to 300 megahertz—while maintaining efficiency.
When FINsix 1’st licensed this technology, the company set its sights on decreasing power converters for Light Emitting Diode (LED) lights. Approximately one year later, when the AC & DC technologies were ready, the company started taking interest on laptop adapters.
In traditional adapters, an array of switches flip to one state & take in AC voltage from a wall outlet, where it's then stored in inductors & capacitors & converted to Direct Current (DC) voltage. The switches then turn over to another state to deliver small chunks of the DC voltage before returning to their original state to the battery.
