HRPWM with DITHER

[User14952]

Hi.

I would like to kwon if it is possible to add the dither functionality (which is included in CCU8) using the HRPWM.

Can be performed using DAVE apps?
Must be included in the code without the help of the DAVE apps?
Is possible?
Is not recomendable due to the high frequency accuracy and / or dead times?

Any comments or suggestions shall be really appreciated.

My equipment will work at maximun 250kHz with phase shift full bridge and probably with Peak Current Mode Control.
Can be applied the Dither functionality for this Peak Current Mode Control?

Best regards.
Carlos.

Hi!

Well on my application I will use XMC4400F100K512BAXQMA1. (Fsw up to 250kHz)

but I also bought the EVAL_1K4W_ZVS_FB_CFD7 which uses XMC4200-F64F256 BA and I would like to test it on the EVAL Kit (Fsw 100kHz)

Regards.

Hi,

Can you please explain more about your application so that we could help you better.
For example, if you want a precision about 2 decimal points in your application then CCU8 and dithering would work well.

Hi,

I have attached the HRPWM code example in the link you also refer to the code example.

Thanks It seems there are many interesting examples.

However have you test the HRPWM with Dither funcionality. It is possible to use HRPWM with Dither?

Thanks for the examples indeed.
Carlos.
