Magnachip Semiconductor Corporation has developed its 1200V 75A Insulated Gate Bipolar Transistor (IGBT) in a TO-247PLUS package, designed for solar inverters.

Magnachip entered the solar inverter market in 2020 by introducing the 1200V 40A IGBT (MBQ40T120QFS) and then offering the 650V 75A IGBT (MBQ75T65PEH). The company has now unveiled its 1200V 75A IGBT (MBQA75T120RFS).

The company says the latest product, packaged in a TO-247PLUS with a wide heat spreader, improves heat dissipation as compared to the TO-247 package. Designed in accordance with the standards of the Joint Electron Device Engineering Council, the company adds the product is suitable for a wide range of applications requiring strict power ratings, including solar inverters, converters, uninterruptible power supply systems and general-purpose inverters.

“With this new product launch, Magnachip’s solar energy power product lineup has been further strengthened and now boasts high-performance IGBTs and MXT MV MOSFETs that satisfy the technical requirements of applications in the solar energy market,” says YJ Kim, CEO of Magnachip.

“We will continue to supply innovative power solutions targeting renewable energy applications and capitalize on growth opportunities within the industry.”

The company plans to start mass production this October.

Metaphysics

Here’s a very short video on the subject of metaphysics, the philosophy of being and reality.

It’s a great example of what I mean when I say that it has been a terrible last few centuries for philosophers.

In ancient times, if you wanted to know what the fundamental building blocks of the universe, you asked a philosopher, perhaps the ancient Athenian Democritus, who propounded the theory of the atom, which was, by definition, indivisible.  Now we refer this question to the realm of particle physics.

Far more recently, those who struggled to know the ultimate nature of reality asked a metaphysician.  Now, once again, we’ve put our trust in science.

I hope you’ll check out the video linked above.

Invest in Small Wind … At Your Peril

As a PhD colleague once told me, “If you don’t care how much of pay for electricity, I’ll get you all the renewable energy you could ever ask for.”

In this case, I’d guess the average price per kwh for the typical American household would be somewhere between $5 and $10.

They want you to invest.  Have you ever asked why people with their own money at stake have abandoned these ideas 20 years ago?

The U.S. Civil War Didn’t Need to Happen

At left we see why Lincoln would have done well to let the Confederacy cede from the Union.  He could have simply written a letter to Robert E. Lee stating:

Keep your slaves and your land…for now. Wait until you experience the effects of near-zero industrial and military technology development and the civilized world’s refusal to trade with you barbarians.  By the end of the 19th Century, a stiff breeze will blow you away. Maybe some future U.S. president will invade you with a troop of Boy Scouts with slingshots, or maybe a handful of banditos will ride up from Mexico.
