The inductor that makes a loud noise is also the one that delivers the greatest power.
So the key to successful induction is not the noise it generates, but the power it delivers.
In other words, it should be loud enough to be heard and not loud enough that it makes the person’s ears bleed.
That’s the approach taken by a team of Canadian researchers at the University of Calgary and the University at Buffalo.
They’ve developed an inductor with a new and efficient design that can deliver up to 40 per cent more power than existing ones.
It’s also much quieter than a conventional induction, which is what makes it the perfect choice for applications where noise is an issue.
“Our current inductors have very little power capacity, so they have to be cooled to keep them from overheating,” said Dr. Michael Schumacher, the lead researcher on the study.
“In our current design, they are cooled in a way that minimizes their noise.”
The team used a design called the inductor power converter, which takes the heat out of the inductors and delivers it to the output.
It was inspired by the cooling process used to cool an automotive radiator.
“We used a liquid nitrogen condenser to produce a vacuum in the chamber that is designed to reduce the amount of heat that the inductators are going to receive,” said Schumachers co-author Andrew Stoll, a postdoctoral researcher at the university.
The cooling process was a major contributor to the higher power output.
In the future, the researchers hope to make it even better by applying different heat-transfer agents, such as a carbon dioxide gas, that can transfer heat from one chamber to another, creating more power.
“This is one of the reasons that we are so interested in making this type of design more efficient,” said Stoll.
“It can deliver higher power than what we’re currently doing.”
The research is published online in the journal Science Advances.
“Inductors have been used for decades in industry,” said co-lead author and PhD student Robert Erskine, who is also an associate professor of physics and engineering at the UBC School of Engineering.
“They are an important component of the power supply of the automotive industry, and they can deliver power much more efficiently.”
The researchers developed a cooling system for the induction.
In addition to reducing the heat generated, the cooling system has a new design that minimises the amount noise.
“By reducing noise, we were able to increase the power output by up to 10 per cent,” said Erske.
The new cooling system uses a new type of heat transfer agent called a carbon monoxide gas.
“When you heat the system, you are releasing carbon dioxide, and that is a powerful heat transfer gas,” said Shumacher.
“As you get more and more carbon dioxide released, you get better performance from the system.”
The cooling system also reduces noise.
When you heat a system, it generates a lot of heat, and the more you cool it, the louder the system gets.
The researchers wanted to find a way to reduce noise without causing the system to heat up, which can make it harder to use the system.
The system uses an electrostatic discharge (ESD) coil to cool the inductance of the coil.
The coil consists of a coil that is made of copper, nickel, and silicon.
When it cools, it produces an electrical current, which flows through a copper wire.
“The copper wire acts like a kind of resistor, and it’s connected to the copper coil that goes through the coil, so when you turn on the induction, you can control the inductive current,” said Chai Kheng, a doctoral student and co-leader of the study from the UB Nanoscience and Nanoscale Science Group.
“If you connect the wires of the current to the coil of the ESD coil, you control the amount that the coil produces in the inductivity of the wire.”
The current that flows through the wire also creates a magnetic field that is transferred to the inductances of the two coils.
“So when the current is generated, it can be changed by changing the inductence of the copper wire,” said Kheng.
“You can also control the current flow in the coil.”
The system has been tested in an electric car that was equipped with an electric motor and a battery, and also in an air-cooled induction cooler.
“A big benefit of our system is that it can operate in all conditions of the vehicle,” said Jody Tait, a PhD student from the University’s School of Mechanical Engineering.
The project was funded by the National Research Council.
“Because this is a technology that’s been around for so long, it’s important to get it into the hands of as many people as possible so that they can make the right
