I would like to know representative values for buck converter parameters

Hello. I am trying to model a photovoltaic system and I need to implement a buck converter. The thing is that I don't know representative and realistic values for these parameters: L, C, RL and RC, as well as the PID controller values.

It is very important that the performance is as close as possible to a real buck converter. Does anybody know about a database or premade dc-dc converter blocks that include the values for commercial products?

Thanks a lot.

hi Ricardo,

The parameters depend on System details such as power, voltage, current, switching frequency, etc. Once these are available, it is possible to compute various parameters using reference books and technical publications.

I'd recommend the following resources for you to have detailed look:

• Useful webinar: https://www.mathworks.com/videos/modeling-and-generating-code-for-a-dc-dc-buck-converter-using-ti-c2000-microcontrollers-1695656394159.html
• Example for above webinar: https://www.mathworks.com/help/ti-c2000/ug/dc-dc-buck-converter.html

Hope this helps.

have a good day.
