Tesla Large Drive Unit Max Voltage

Post by Joxson »

Hey Guys!
Was searching the threads here and couldnt find a answer to my question. Does anyone know if it it safe to run 108S on a Tesla large drive unit?
And can the evbmw controller board handle it?

Best regards!

Should be fine, the igbts are rated for 600v. So 450v full charge leaves a bit of room for voltage spikes. With proper tuning to minimize voltage shoot through

The openinverter board doesn’t care what you run the power stage at.

The LDU inverters DC-Link caps are only are rated for 450V so anything above that will be at your own peril.
