It was TDA. Now we have some spin. Time to tinker with resolver offset. UPD. Got some decent RPMs and almost found good syncofs . But half-baked IGBTs finally decided to die. RIP. Will wait for new inverter now. While it's been delivered I will apply some fixes to my logic board, also rework wires e...

Ok. First, some problems with current sensors were solved. Now it calibrates just fine. Also, there were some strange shenanigans with protection circuit comparator and input/output logic. Also solved. Second, I found cross-layer short-circuit on IGBT board and restored and replaced everything damag...

johu, thx, will check input dividers tomorrow. A bit confusing. We have 3k3+4k7 on mainboardv3.4.pdf from git, only 3k3 for v2 board wiki (https://openinverter.org/wiki/images/a/a1/Schematic_main_v2.png), mainboard_mini has 3k3+6k8 as you suggested and as far as I can remember, mine is 3k3+10k which...

Ok, we have an issue with both current sensors. They show around ~2,45 volts on outputs with zero current - hapf supply voltage or so. It's too much, should be between 1,23 and 2,06 vots. So we have permanent HICUROFS1/2 and OVERCURRENT stop. Is it possible that our sensors are damaged? Which sensor...

Ok, we're definitely alive here. At least WIFI web-interface yields legit errors and numbers. Overall it consumes like 500-600 mAmps from 12V psu. Gonna test with engine and HV supply on upcoming Monday-Tuesday... Wish me luck! =)

Well... Should be something like this.
Please correct me if I'm wrong here.

johu, thank you. But I asked about IGBT Drivers Board pinouts. Not about OpenInverter board. As i said, I don't have stock cables. I can tell where all six PWM signals go, but I'm not sure about FAULT1, FAULT2, UDC_PWM, heatsink temp and both current sensors. I'm talking about this board and sockets...

Good day everyone. Right now I'm working on Leaf-related project - my friends are building custom electro-bike using Leaf powertrain. And I'm making inverter control board for them. We have good engine, 90%-probability-good driver board, battery assembly (now balancing) and toasted inverter logic bo...
