I
recently
bought
an evaluation board
STEVAL-IHM025V1 and I am having problems to make it work. I want to control a three phases induction motor.
The board is supplied with 230VAC, and I can see the DC bus voltage equals to 325Vdc.
I create 3 PWM with a DSPic33e, they are correctly shifted to control a 3 phases induction motor. After I control my device with this signals but the outputs aren't what I expected.
I visualise the same signal for the three ouptuts, a sinus signal with a 150V amplitude with no shift.
The pin SD is correctly control.
So I don't know where is the matter, if you have any idea!
Thank you.
Benjamin L.
