I'm attempting to use the stock gen2 Nissan Leaf inverter with a lebowski controller. I've seen Tomdb do this with a Chevy Volt inverter (my backup plan, I've seen them cheap used) I still have to build a control board but I'd like to share my findings on the free inverter that came attached to my Nissan Leaf motor. Bear with me as even with an electronics background, I'm struggling a bit to understand.
The cable that plugs into CN601 on the control board connects to the power stage in the last picture. Pin out is as follows one wire going to each driver input :
pin 1) WN
pin 2) WP
pin 3) VN
pin 4) VP
pin 5) UN
pin 6) UP
pin 7) blank
ground?? see photo, goes to each of the 6 drivers
Each IGBT is connected by a row of pins on each driver, this row of pins is labeled CNWN and so on for each driver. I've seen each phase labeled as W, V, and U. I'm guessing the N is negative and the P is positive. The IGBT is one long unit under both the positive and negative drivers.
Connector CN101 at the control board supplies 12V and ground:
Pin 1 and 2: 12V
Pin 4 and 5: ground
Connector CN151 at the control board has the 2 current sensors, one on V and the other U. 4 wires from each current sensor. I haven't looked to much at these yet but wondering why there are 4 wires.
Then there is a connector CN501 with 12 wires that plugs into the far right of the first picture, all these are unknown.
So with the proper lebowski controller will this power stage work? I already have it, it bolts nicely to the motor, I'd like to use it. I like Arlo's controller build, not beyond me but looks like a lot of work and money that I could use elsewhere.
