400V 500A inverter

Threaded View
Tesla Model 3, 400V 500A 3-phase inverter,
description and annotated images,
http://www.inventchip.com.cn/pages/tesla%20model.html

Earlier we were discussing, struggling how to best  
get the heat from SMT mounted DPak transistors onto  
a heatsink, likely one on the bottom of the PCB.

Images 6 to 9 shows Tesla's approach, with 24 GK026
ST SiC MOSFETs (they don't show up on ST's webpage).

They are violating the one-resistor policy.

The whole world will eventually go from dirt poor to sort of middle
class. Everybody wants electricity and clean running water and beds
and windows in their houses. Most people want heat and eventually a/c.
China and Africa getting better doesn't diminish us.

That progress will take a lot of energy.

  Bullshit.  We produced in Hong Kong.  China was given a gift when the  
UK gave the back the region.

  We could produce all those chips and DVDs here.  But they would mean  
that you PAY a lot more for things and growth and technology growth  
actually slows.

  No cinese cars here...  No chinese car parts here.

  You make too much shit up, boy.  You ARE sorry.

The problem with DT's anti-globalist rhetoric isn't so much that it's  
wrong it's that it's a) mostly lifted from the Left who've been saying  
it for 30 years and b) it's all about 30 years too late.

What's really amazing is that _now_ you hate the idea because Trump is
actually doing something about it.  Leftists truly are idiots.  Every
one of you.

Wrong. Everybody hates Trump's anti-globalist rhetoric and actions because  
his trade wars are putting a crimp in the global economy, the US economy in
cluded.

The real idiots are people who think that anyone can win a trade war.

Trump isn't actually an idiot, but his unwillingness to pay attention for m
ore than a few minutes at a stretch lets him fall for solutions that look g
ood in the short term, but lead to long term disaster, which is pretty idio
tic.

Krw uses the term "idiot" in a rather specialised sense. For him it means "
somebody who doesn't agree with krw". In this particular krw is being obvio
usly idiotic, and he's much too rigid in what passes for his "thinking" for
 him ever to be able to realise it.

Krw is confused by situations where one can hold mixed views about a  
person and be vaguely pleased with one subset of their actions, yet so  
displeased with another that it outweighs any goodwill the former has.

These types of normal human emotional states cause his subroutines to  
throw an error code.

You think that was done on purpose?

I see a lot of expensive advertising that is such bad English that it
must hurt sales; sometimes you can't tell what they are trying to
sell. That would be an expensive joke.

Engineers anywhere and everywhere often have a wry sense of humor. The  
rest of the English on the page seems pretty good. Better than many  
native English speakers write in e.g. job applications, matter of fact.

Well whaddya want from a bunch of "Communications" majors from Wayhuge  
State Sportsball University. I went to a dedicated liberal  
arts/humanities school, there's a _lot_ of writing involved in those  
curriculums, and people actually do read what you write and rip you up  
and tell you it sucks if it does, in fact, suck. it's not all

It's the kind of place that actually turned out published authors moving  
multiples of 10k units of a book. I know secondhand that when you start  
moving kilobook volumes of a novel you're makin' real author money,  
enough to afford a one bedroom in Oakland, surely and eat out at  
Applebees from time to time. Woohoo!

It's a genuine error alright. For some reason, Chinese have trouble
distinguishing 'r' and 'l'. Still, their English is better than my
Chinese.

The reason is well known. The international phonetic alphabet distinguishes
 some 200-odd phonemes, and most languages restrict themselves to rather sm
aller group of phonemes - English uses 44, though different dialects of Eng
lish may get by with less. One Polynesian language gets down to 11, and one
 of the South African click languages has about 120.

https://en.wikipedia.org/wiki/International_Phonetic_Alphabet

English - like most European languages - treat 'r' and 'l' as separate phon
emes. Chinese and Japanese don't. Once a child has learned the phonemes of  
their mother tongue, they learn not to pay attention to differences between
 phonemes that don't matter, which happens at about the age of six months.

You can learn to hear the differences again at any age, and phoneticians do
, but it's a little more demanding than just learning a new language.

Aside from a few dropped articles the English in the rest of the  
document is fine, almost indistinguishable from a native speaker, and  
they don't make an error like that anywhere else, though.

Perhaps the images were annotated by someone other than the text's author.

  Us hands on folks noticed this decades ago as it first started  
appearing in motherboard manulals.

  There were some seriously funny writings back in the early days.

  The stuff around now is tame by comparison.
