Other Parts Discussed in Thread: UCD3138ACCEVM149,
Im using UCD3138ACCEVM149 with UCD3138ALLCEVM150
I downloaded the LLC firmware from TI ,which has a default 80kHz resonant frequency for UCD3138ALLCEVM150.
When I try to change the resonant frequency from 80kHz to 450kHz im getting negative frequency reads from monitor which is very absurd.
I know that UCD3138ALLCEVM150 hardware does not designed to be work on high frequency ranges like 450kHz . Only thing I m trying to see is that " can I change the frequnecy limit by using Fusion Digital Power Studıo" only.
In my case , is it possible to change frequency limit by using Fusion Digital Power Studıo or should I modify the firmware using "Code Composer Studıo" ?
What is the reason for negative frequency readings ?
These are the results for firmware with default settings. Everything is working as expected.
These are the results when I change the resonant frequency to 450kHz , gettting negative frequency readings.
These are the modifications that I have made.
Also I ve changed the "dead time" parameters to 150ns.
