Hi Alikaan,

Can you send a screenshot of enitre board and point to this place? Because the UCC5880INVERTER EVM doesn't have any 3 pin headers. I have check the layout and have the original board with me as well. Looks like a different board or old version or something else

Best,

Pratik

Hi Alikaan,

That board isn't the gate driver (UCC5880) board. Looks like MCU control board. Have looped in a different team to respond to your question. Appreciate your patience and understanding.

Best,

Pratik

Hi Alikaan,

The requirement for the positive and negative power supply comes from the LEM sensors and that is typically the case. The sensors used in this design are LEM LF510-S.

Kind regards,

Ivana
