FPGA for power processing control unit

Hi,

Can anyone suggest a FPGA for power processing control unit.

Below are the system specifications

  • Thruster – Hall Effect Thruster
  • Thrust Power Level:- 1.25kW to 5kW
  • Anode Voltage :- 200V to 400V
  • Cathode Supply :-   Programmable Ignitor High Voltage and Heater Current in order to match different Ignitors and Heaters
  • Input Power Bus Voltage:- 100V or 50V regulated bus
  • Input Bus Protection :- Galvanic Isolation
  • TM/TC I/F :- MIL-STD-1553B

Control section requirements:

  • Thermal sensors acquisition
  • Thruster driving voltage and current acquisition
  • Heater driving current acquisition
  • Output voltage and current signals acquisition
  • Voltage set to DC/DC Converters for Anode, Cathode and Magnet coil
  • Operating modes management: start-up, stop, regulated thrust and failure recovery
  • External Telecommand/Telemetry communication

Please do the needful.

 

Regards,

Shilpa

Re: FPGA for power processing control unit

If your system also need to have custom OS or system then Zynq 7000 or Ultrascale+ MPSoC could be the solution. While you may review the product selection guide of specific FPGA. Zynq family is preferred for Embedded Applications!

Other FPGA familes like Spartan and Artix might be cost effective solution for your application.

It is just an personal view!

Re: FPGA for power processing control unit

All the things you've described could be handled by a cheap microcontroller - depending primarily on how much processing you want, what sort of hard-realtime guarantees you need, what sort of interfaces you need, etc. As such, those are really the key design requirements to specify before choosing an FPGA.

Thanks Krishna..
I think FPGA from Zynq 7000 or Ultrascale+MPSoC family is suitable as the system includes the high speed communication which involves GTX differential pairs.
