PowerBD

Evaluation of STM reference boards: powerBD-3000 and ControlBD-7FMC2

 

powerBD-3000

ControlBD-7FMC2 is CPU board that is pluged to powerBD-3000

Target of the project is to make the eval-boards work ASAP as induction motor driver

Additionally

Create new schematic and pcb cad-file.

Evaluate the Software Tool Chain.

Why

• Compare with Freescale MC3PHAC solution already tested
• Test the non isolated (lower cost than isolated) power-stage
• Have STM solution

STATUS

Project Initialise

Key-points

• Try to transfer STM orcad schematics.
  
• Make the boards work as open loop induction motor driver.
  
• Test for 48-60V DC Input, Then with rectified 220V-AC
• Evaluate ST7FMC2S4T6 -->most-important-link<--, ST7 series motor-control 16KB-Flash microprocessor.
  
• Install and test the ST72 tools from STM and others.
• Try to use ANGLIA-idealist open-source ST72 tools.
• Use of evaluation version COSMIC C-compiler ..Limited to 2KB.

Fast Data

• powerBD-3000 is 3KW 3phase driver evaluation board. IGBT driver IC's are not on board
  

• ControlBD-7FMC2 includes the ST72 CPU and 3x 600V half bribge IGBT/MOSFET drivers
  

• No electrical isolation from load to CPU.

• Used IGBT's are STM/ STGW20NC60VD/  60A/600V/TO247/ N-CH/ Vce(on)=2.5V @ 15V,20A/  DIGIKEY 497-4357-5-ND/ PRICE $6.47/1, $4.73/100
  

• powerBD-3000 part-number is STEVAL-IHM005V1 / Digikey Price $73, 0-stock @ 2011.06.17
  
• Idealist is open source IDE uses GCC C and C++ compiler, GDB, openOCD for STM7, but is not updated since some years....
