Great read on the evolution of EV power electronics. The NYT link is supposed to work for sharing the article. I'll copy a couple of paragraphs below.

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. “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. “Scaling down inverters enabled its streamlined design.” 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. (It also made Tesla one of the most valuable companies in the world.) -------------- next part -------------- An HTML attachment was scrubbed...
