Part Number: TMS320F28388D
Hi experts,
I have a question about a below restriction.
We need 2-phase modulation in our motor control application like below.
However upper limitation have a trouble in our implementation.
(Our targeted modulation)
It is too difficult to estimate "yellow rectangle event" at one previous period timing
because it depends on output of feedback current loop control.
U, V, W phase modulation values are changed from 0 and period (Yellow rectangles on below figure)
Could you please provide a work around information ?
And if +1 and (period -1) on CMPA/B, it generates a small pulse on one side with deadtime,
it is not a work around for us.
In ePWM block, AQ submodule generate a very small pulse but DB Submodule add dead time on a pulse.
Could you please provide a comment to avoid this behavior ?
Best regards,
Hidehiko
