Power System

  • Requirement is to develop a system that

    • Supplies required voltages and currents

    • Provide PS housekeeping measurements

    • Very low noise

  • Present approach-- develop PS for T/V test that runs the electronics

    • Use VICOR recommended filtering (very likely inadequate for ANITA flight)

  • After T/V test, work on noise reduction


Power system components for t v test

Power System Components for T/V Test

  • Cables

    • 24 V Input Cable--IP Box to DC-DC Conv.Box; +24, +12, -12

    • cPCI Power Cable--DC-DC Conv. Box to cPCI; +5, +3.3, GND

    • cPCI Power Cable--DC-DC Conv. Box to cPCI; +12, -12, +5, +3.3

    • Turf power Cable--DC-DC Conv Box to Turf; +3.3, +2.5, +1.5, -5

    • 2 Housekeeping Cables—DC-DC Conv Box & IPB to HSK Cond box; HSK signals

    • Cable into T/V made in Palestine

  • Bus Bar Board

    • Originally suggested by PD, but based on misconception of cPCI crate

    • Not needed since cPCI crate provides excellent grounding

  • DC-DC Converter Box

    • 7 boards at present—Room in box for an additional 2 boards

      • +12V at 1A

      • -12V at 1A

      • +5V at 30A

      • -5V at 2A

      • +3.3V at 25A

      • +2.5V at 16A

      • +1.5V at 2A

  • Instrument Power Box

    • One DC-DC Converter; Room for two more

    • Relays

      Only three used for T/V test

    • Charge controller- in box but not hooked up for test
