Suitable STM32 for adjustable dc-dc power supply

[erol_ozkarsli]

Hi everyone,

I plan to build 0-60 volt 30 Amps adjustable (menu driven) lab power supply both ac and dc(battery) input

I'm new at st mcu and need some advise about choosing right device both controller and user interface.

thanks inadvance.

Welcome @erol_ozkarsli, to the community!

This request is extremely unspecific because the community can imagine anything from a complete power supply control to a ready-made power supply block that is (only) controlled by a controller. You didn't even give any details about the user interface: Potentiometer with pointer? Seven-segment displays? Graphic display? After all, you are talking about a power supply unit that is supposed to deliver up to 1.8kW.

What does your first brainstorming approach look like?

Regards
/Peter

Hi Peter,

You are right, sorry for unclear request about project and myself. 

Let me give some details about PS that I plan to build; 

It will be the Buck Converter PS due to its high efficiency, simplicity, and capability to handle varying loads effectively.

Implementing PWM control, feedback loops for voltage and current regulation and addressing light load conditions  

make it versatile PS that meets my requirement.

There is no question about Power Stage I already use TI piccolo MCU (F280041C) for simulation which I am familiar with, and because of some difficulties obtaining TI products I replace it with EU made ICs and ST is my first choice

that's why I ask for help to find out the right MCU.

thanks for your understanding 

Regards

As @Peter BENSCH  said, your question is vague in the extreme and, therefore, impossible to answer.

Are you familiar with any other microcontroller(s) ?

Do you have electronics design experience - particularly with high-power supplies ?

Hi Andrew.

Thanks for your response and advices,

Hello,

(I'm not power supply design expert)

Look at the STM32F3 or STM32G4 series:

As you've already used another MCU for the same application, better to make a comparision with what you have used in it with what is available in the F3/G4 series.

Are you looking to use a HRTIM (High resolution timer) or a generic 16/32bit timer?

Look also at this video presented by an ST partner, I think it may give you an idea (using STM32G474 MCU).

Hope that helps.
