• Who

  • @Daniel Puratich idea

  • @Tim Gu looking into it

• What

  • Take in 12V and output 24V

  • For powering our 24V battery charger

    • would be massive help at comp and flight tests to be able to charge faster

  • Supply enough power for the charger

    • if the current is really high then this project is going to be waaay out of our skill range

• Why

  • We have 12V server PSUs that are CSA approved

  • We get more power capability out of the charger at 24V

  • we could also just buy this? not sure if it maths out.

  • What is the output current/power rating?

  • Whichever convertor we choose should be able to handle the same amount of power that the PSU outputs

COTS options:
