Traction Inverters

When Tesla released its Model 3, it had a secret technical edge over the competition: a material called silicon carbide. One of the key parts of an electric car is the traction inverters, which take electricity from the batteries, convert it into a different form and feed it to the motors that turn the wheels. To get the pin-you-to-your-seat acceleration that Teslas are known for, traction inverters must pump out hundreds of kilowatts, enough power to supply a small neighborhood, while being dependable enough to handle life-or-death highway use.

There is nothing secret about silicon carbide, a.k.a. carborundum and moissanite. One good way to lose money with silicon carbide was to invest in Cree now know as Wolfspeed

The company was founded in July 1987 in Durham, North Carolina. Five of the six founders – Neal Hunter, Thomas Coleman, John Edmond, Eric Hunter, John Palmour and Calvin Carter – are graduates of North Carolina State University.[2]

Silicon carbide

Silicon carbide (SiC), also known as carborundum (/?k??rb?'r?nd?m/), is a hard chemical compound containing silicon and carbon. A semiconductor, it occurs in nature as the extremely rare mineral moissanite, but has been mass-produced as a powder and crystal since 1893 for use as an abrasive.

Oct. 9, 2013
As an alternative to traditional silicon MOSFETs, silicon carbide MOSFETs offer the advantages of higher blocking voltage, lower on-state resistance, and higher thermal conductivity. The devices can replace silicon MOSFETs and IGBTs in many applications.

The NYT has managed to transition from being a leading newspaper to a JOKE.

And I thought the Times had a scoop.

Cree/Wolfspeed is now near its all-time high.

How is that losing money?

Alan, are you up to date with verb tenses? :wink:

was to not is to

Cheers!

Verbs come in three tenses: past, present, and future. The past is used to describe things that have already happened (e.g., earlier in the day, yesterday, last week, three years ago). The present tense is used to describe things that are happening right now, or things that are continuous.

Daybreak in Central Park, a cup of coffee, and the Sunday NY Times; doesn’t get much better than that!

I am planning my last trip to NYC. Central Park. The Village Vanguard and Yankee Stadium.
