TIDM-1000: Trouble at first starts of TIDM100 board

Part Number: TIDM-1000

Hello everyone,

I am currently working on TIDM1000 board, I am familiar with model, vienna PFC, board, control law and control card, I am running Build level 1 in open loop but I have a problem with the L-N signal (I insist on signal, not measure) :

Instead of sin L-N voltage I have this (third curve) :

I have the same signal with oscillo (the measure is good), L-L measure is a sin, and I am working with 390ohm load.

In all document about TIDM1000 I can see a good sin and only "one peak current" curves, do you have an idea about my trouble ?

Anyway, your products, tools and boards are amazing and it's a real pleasure to work with you !!

Thank you very much and have a nice day,

Best regards,

Jérémy
