New Technology Behind the World’s Smallest Power Converter – Science and Technology Research News



The advancement of future smart phones and laptop computers concentrates on additional reducing the size while increasing the speed and including new functions.

Today, a cellphone is not simply a phone however a whole interaction and home entertainment centre total with cam, GPS, web internet browser, sensing units, video gaming centre, and a lot more.

The energy source for smart phones is either a USB cable television plugged into a power grid or a battery. Nevertheless, the electronic parts for the various functions in the phones are powered by various voltage domains.

A power supply system for that reason makes sure that the voltage is transformed from USB or battery to the lots of voltage domains. Frequently, as much as 15 various voltage domains are required, each of which needs a power converter. The lots of power converters hence use up a great deal of space.

Traffic jam for attaining smaller sized size gotten rid of
The interest in developing smaller sized power converters is hence fantastic. The huge difficulty now is temperature level. The little electrical circuits can quickly warm up to 80°C, which is neither preferable when holding the phone in your hand, nor safe as it increases the threat of brief circuits and fire.

“For our new technology, we’re using a new material as a base for the electrical circuits in the converter, and that’s silicon. Silicon prevents the formation of so-called hot spots with very high temperatures. The new converter will reach a maximum temperature of about 45°C, and that’s perfectly acceptable,” states Yasser Nour, DTU Electrical Engineering, who is among the scientists behind the new converter.

“Silicon also has other advantages, because it can be found in large quantities in nature and is thus both sustainable and inexpensive to use,” he includes.

On top of the silicon, the scientists incorporate the numerous active and passive parts in the converter. This is done by stacking them up in three-dimensional layers, nearly like a 3D printer.

Terrific interest from services
The marketplace for the new converter is substantial, not just in smart phones, however likewise in, e.g., laptop computers, hearing help, or wearables, which continually check out information from your body or from the environments.

“These electronic devices also need to be able to process ever increasing amounts of data quickly. They therefore require more power, while they still need to be as small as possible. This is where our new technology really comes into its own,” states scientist Ahmed Morsi Ammar, who likewise took part in the advancement of the converter.

Yasser Nour, Ahmed Morsi Ammar, Pere Llimós Muntal, Dennis Øland Larsen, and Hoá Lê Thanh are presently dealing with beginning their own company based upon the recently established power converter. The very first prospective consumers have actually currently registered and will quickly get a test transformer, so that they have the chance to check it themselves.
