DSC LLC 2P2Z parameters

HI, All

In DSC56F81xxx LLC project, the outer voltage loop use the 2P2Z control. How to get these parameters(B0, B1, B2, A1, A2)? If I modified the part hardward, is there the software tools to help us to calculate these parameters? Hope to your help. Thanks!

Hi,

I think you can use the Matlab tools to get the response either in frequency domain or in time domain.

We have a free tools to get the frequency response,Qedesign lite.

You can download the CodeWarrior for 56800E ver8.3, after you install it, the Qedesign lite will appear as above screenshot.

You can download the CodeWarrior for 56800E ver8.3 from the link:

Special Edition: CodeWarrior for 56800/E Digital Signal Controllers - code size limitation: 64Kb

Hope it can help you

I could not use this tool rightly. Do you have the instructions about the 2P2Z parameter design by Qedesign lite? Thanks!

Hi, Xiang,

Pls download the an3599 for the Qedesign tools from the link:

https://www.nxp.com.cn/docs/en/application-note/AN3599.pdf

It discusses the IIR parameters from Qedesign tools.

Hope it can help you
