T E S L A motor controller view

[Doctorbass]

The popular TV show HOW IT'S MADE recently presented the TESLA S construction.

It was particulary interesting to see how the TESLA motor controlle is built and we can see a clear view of inside of it.

look like they are using IGBT but i can see some To-247 style in row of 7 units... are they?

This is a crop of the section the good doctor linked to:

Fairchild’s SiC BJTs are available in a TO-247 package. Engineering samples are available for qualified customers.

SiC BJT versus other SiC devices

Fairchild lists the properties of its SiC BJT devices (compared with other SiC devices) as follows:

Most efficient 1200V power conversion switch ever made (the lowest total losses, including switching, conduction and driver losses, and the lowest switching loss at any given RON, of all 1200V devices);
Straight-forward driving (normally-off feature reduces risks, complexity and performance limiting designs; stable base input that is not sensitive to over/under-voltage peaks); and
Robust and reliable (high-rated operating temperature of Tj=175°C; easy paralleling due to positive temperature coefficient for RON and negative temperature coefficient for gain; and stable, rugged Vbe forward voltage and reverse blocking capability).

Attached is the 34 seconds of the video where the inverter is shown, for those in the USA that can't see the youtube video or download magnet links. 720p video, around 30MB.

Awesome, thanks.

While watching the whole documentary, the machine I most wanted to see was the stator winding 'bot. However all the magic was hidden from view by the casing .

What a great video, thanks for sharing

The inverter is impressively compact, but I found the motor winding process to be more interesting.
