“I want to be the first to welcome you to Silicon Carbide Valley, because this is the future.” You ever hear of that? Yeah, it’s kind of overrated,” she said. “There’s a little place far away called Silicon Valley. Kathy Hochul talked up the Wolfspeed plant at its opening ceremony. Experts say the collected information could also improve road safety. Car Crashes: Tesla and other automakers capture data from their vehicles to operate their products.The high cost of electric cars and gasoline have given them an opening. sales of plug-in hybrids have been surging.

(It also made Tesla one of the most valuable companies in the world.) The Model 3 was a hit, thanks in part to its groundbreaking power electronics, and demonstrated that electric cars could work on a large scale. “Scaling down inverters enabled its streamlined design.” “The Model 3 has an air-resistance factor as low as a sports car’s,” Masayoshi Yamamoto, a Nagoya University engineer who does tear-downs of electric-vehicle components, told Nikkei Asia. STMicroelectronics, the European company that produced the silicon carbide chips Tesla used, claimed that they could increase a vehicle’s mileage range up to 10 percent while saving significant space and weight, valuable benefits in automotive design. While previous traction inverters had been based on silicon, the Model 3’s were made from silicon carbide, or SiC, a compound that contains both silicon and carbon. The company had released two successful luxury car models, but in its effort to become a major automaker, it gambled the company’s future on making a cheaper, mass-market vehicle. This wave of new materials burst from the lab in 2017, when Tesla faced a pivotal moment in its history.
At a time when supply chains for silicon are severely kinked, these newer materials have boomed.
Some novel, post-silicon devices are in use already, and better power electronics will become far more important in the future as much of our economy switches from fossil fuels to electricity. This field, aptly called “power electronics,” is changing quickly as engineers switch to power-control devices based not on silicon chips but on new materials that handle electricity more quickly and efficiently. Moore’s law has become a well-known summary of how those chips become ever more compact and powerful.īut electronics also have a critical, less celebrated role in modern life: directing the electricity that powers all of our gadgets.
The story of modern electronics is often equated with the relentless advancement of the silicon-based microchips that process information in our computers, phones and, increasingly, everything else.
