You’ve probably felt a twinge when you see them: the small red power light on your high-definition television or the phone charger you forgot to unplug.
You know the vampire current is sucking just a little electricity and that your carbon footprint could be a bit smaller if you took a few seconds to pull the plug from the wall outlet.
Those tiny watts of vampire power add up. If everyone in the United States simply unplugged unused chargers for the cell phones bought in a single year, the energy savings would be enough to keep the lights on in a city of 200,000 people. Extend that a few years and imagine the power plants that might not have to be built.
The vampire is working elsewhere, as well. It’s gradually drinking power from high-voltage applications such as electric vehicles, factory robots, telecom base stations and vast data centers.
But help is here.
Today, power supplies – the tiny circuits that transfer and convert power in devices of all sizes – are able to achieve higher density, lose less power, and create less heat and signal noise because of innovations in circuit design and the use of groundbreaking semiconductor materials such as gallium nitride (GaN).
As a result, the evolution in power delivery is enabling system developers to use smaller, more efficient circuit boards for high-voltage applications.
That translates to a greener, more energy-efficient world.
Our commitment to innovation and our expertise in power design is playing an important role in this transformation. Read our white paper – Evolving high-voltage power delivery through the power process chain − to learn more about how we’re innovating to enable greater power density.
