Open source Tesla inverter driver design questions
Posted: Mon Mar 03, 2025 1:31 pm
First time posting on the forum, hopefully this is the right area
I've started looking into the project ( https://github.com/damienmaguire/Tesla- ... ree/master ) and can't figure out why the DESAT pin of the low side driver is connected to the SENSE pin of the high side driver through a 1k resistor and a diode (R1481 and D481 for phase A)? Why is the SENSE pin of the high side driver not connected to its GND_ISO?
Another question I have is regarding the depletion MOSFET and the 3x1M resistors that connect between the high side gate and low side source (Q51, R193, R196, R267)?
