Selection of DSP/MCU

Greetings Community members!!!,

I've got a project to design a variable power supply(major specs below) which can drive a triangular current of ~40A (DC to 15Hz) through a RL load of 0.8Ω+40mH with available source of 3-phase 415V.

I made a basic scheme as attached, As I'm new to this arena I'm unable identify suitable DSP or MCU unit for my project.

Can anyone help me out in selecting the suitable DSP/MCU and reference designs???

Major Specs:

Output Voltage:90V

Output Current:40A

Input Voltage: 3-Ph, 415V, 50Hz,

Regulation: 1%,

Control: 0-10V signal(preferred), or RS232 or any other

  • Sharan, hello and thank you for your interest in TI Designs. You query has been forwarded to our Power Supply Design team for review and response as it is applicable. Please allow 1-2 business days response as some of our engineers are still coming back online from the holiday season.

  • Hi Sharan,

    Please take a look at the C2000 Delfino microcontrollers  

    Delfino devices are very well suited for these applications, especially when you want to use a single controller to control multiple power conversion stages in the system. 

    You might also find the following Vienna based 3-phase PFC solution quite useful.

    I hope this helps.
