Hello InstaSPIN community,
We are using the F2806x ISO controlCARD connected in a power board with the circuit below (Fig. 1) connected in an AC Induction Motor 4KW – 28V – 117A – 2530 RPM, my VDC is a battery 48V – 500Ah . And all the labs worked well.
In the circuit of the Fig.1- Phase A of the power board. The time to the power mos-fets (Q1-Q2) turn on is longer than to turn off.
Lab2b - 3a - 3b - 5c - 5d - 5e - 12a - 12b worked well
Then we develop our power board with the circuit below (Fig. 2). And the labs worked well until lab 12a, the lab 12a doesn't work (the motor does not spin).
In the circuit of the Fig.2- Phase A of the power board. The time to the power mos-fets turn on is the same that to turn off.
Lab2b - 3a - 3b - 5c - 5d - 5e worked well. And Lab12a didn't work.
We have tried to change the dead time HAL_PWM_DBFED_CNT and HAL_PWM_DBRED_CNT without success.
Is there any parameter that I can change to the lab 12a works with the circuit of the Fig. 2 ?
Thanks in Advance !
