A team of scientists has built a simple, cheap and simple-to-use inductor that’s used in laptop computers and other electronic devices, and they’ve put the idea to the test.
The researchers, led by the University of Texas at Austin, demonstrated that they can turn all of the power that’s currently flowing through a laptop’s AC power supply into a passive, low-power mode.
“The basic idea behind this is that we’re able to turn power that we normally need for computing to energy that we can then use to create more computing,” said Jody Tannenbaum, an assistant professor in the university’s College of Engineering and Computer Science and lead author of the study.
Electronics that can be powered by low-level low-voltage AC are rare in the real world, and for many years, they’ve been relegated to the fringes of technology.
But with the advent of USB-C, the high-performance power delivery standard for laptop computers, the possibility of making laptops run at high speeds is gaining traction.
This makes the idea of using the power supply directly to power devices and electronics a big possibility.
It’s a new development, but the researchers were already building a simple inductor to do just that.
The team’s version of the device is called the mAIC.
Its main advantages are that it’s cheap, simple to manufacture, and it can be built for almost any device, said Tannengbaum.
If you can make a high-power inductor for any particular application, it will be a good choice for a laptop.
“If we were to make a computer for the home, for example, we could probably get away with making this simple inductors because we can make them for a wide range of uses,” Tannenberg said.
To make the mIC, the team used a standard process that includes making a plastic sheet that can form a coil.
The sheet can then be coated with an amorphous plastic material that’s known to be a suitable material for inductors.
A heat gun is then used to melt the plastic, which then forms the coil.
Tannenberg, who is a member of the research team, said the team was able to get the coil to work without any modifications to the circuit board.
As they showed, the mAHIC’s low-cost, easy-to use, and relatively small size makes it ideal for many applications.
When a laptop is powered by AC power, the device’s AC input is turned into a high voltage that is then passed through a low-current power supply.
That high-voltages then supply power to the computer’s CPU and memory, making the laptop run at a higher clock speed.
However, when a laptop isn’t powered by the AC power source, the low-volts are still being supplied to the laptop, causing the CPU to run at slower speeds.
In other words, when the power source is not present, the CPU is operating at a lower clock speed, which means the laptop’s processor isn’t being used to its full potential.
So what’s going on here?
Trenenberg and his team built a low power inductor by creating a series of parallel lines that connect the mahic to the power grid.
Their method of making this system was simple.
They built the inductor in such a way that the coil could form a series, alternating wire loops.
Instead of making a single coil of parallel wire, the researchers built three coils of parallel wires that form a ring.
At the end of each ring, the coils join together, creating a ring of alternating wire.
Once they’d created these alternating wire rings, the scientists cut each coil into a ring and made a single, parallel wire loop that was then connected to the mAhic.
With their method of creating the mAni, they were able to control the amount of current the mAc-1 was producing and the amount that the CPU was using to run.
And, by connecting each mAHic to a separate, parallel ring of wires, the system could control the voltage levels that the mAs were delivering to the CPU.
All of this was achieved by using a series resistor to direct the AC voltage.
These devices can be made to work in any power source and they can be manufactured at low cost.
The team plans to build a series-based circuit board to make their mAHi even more efficient.
While the mAtIC is already making its way into laptops, they hope to eventually make a mAI that can handle any power supply, from a DC to an AC to a low voltage.
“The mAHI will become an industry standard in the next couple of years,” Trenenberg said, adding that the team is
