Have you seen voltage rating on that thing?

You can't reliably handle 1500V+ voltages in solid state electronics without purpose made IGBTs, or exotic semiconductor materials.

Your EE knowledge doesn't seem to be more than cursory.



It has a maximum voltage rating of 100V, so you would need 100 in series, with leak resistors to prevent any one avalanching. This is how most modern high voltage switches work, because IGBT's are far less flexible.

Take apart a tesla Model 3 motor controller and let me know what you find...


To begin with, Tesla's "motor controller" is an inverter. The charger on board is AC-DC. DC-DC

It's an old, but still not completely solved problem: imagine your stack open, but for a single FET, and your resistor is a little bit off. It instantly pops, and the "tuning" for the rest of it is now completely off, and it will cascade further

In case of Tesla, they do use the exotic semiconductor materials I mentioned above. SiC goes to 1500V nominally

You need to learn electronics engineering beyond wiring Arduinos

There is old, but still quite good and relevant explanation why stacking FETs suck on edaboard https://www.edaboard.com/showthread.php?269261-Is-MOSFET-in-...

There is an even older, but still excellent paper published by Philips called "Power Semiconductor Applications" where they explored nearly all trick to make FET stacks to work reliably.

Short: it's near impossible to do it reliably with off the shelf part, and it's better to not to risk if you deal with 600A+ currents. And if are determined to do all tricks necessary, IGBTs or III-V materials will still win on simplicity and cost


People have taken apart the Tesla Model 3 inverter and we know what they've found. Here's a hint: it's not a stack of 100V MOSFETs in series.

Depending on the model (SR+, Performance, etc), it's either SiC MOSFETs or IGBTs. And there's only one in series, not 10 or 100.

Also, please do me a favor and never design power electronics ever...
