Revision as of 20:47, 22 November 2007

The 2008 power supply circuit uses the same switching topology as the 2007 system with some changes, most notably a jump in system voltage to 12V from 9V to support the new motors. Another change is more analysis in the design phase including looking at possible interference with the radio and other devices that use oscillators.

Tasks

  • [ ] Finalize specs on voltages, maximum current draw, and allowable frequencies
  • [ ] Select a part based on the spec
  • [ ] Determine how to mount batteries
  • [ ] CAD the design
  • [ ] Verify the design
  • [ ] Fabricate

Specifications

Power Supply

  • 12V operation
  • Small package
  • Low inductance
  • High allowable RL (so we can use smaller inductors)
  • Frequency does not interfere with other electronics
  • Protection Circuitry (TVS:Transient Voltage Suppression)
  • Matrix of Potential Power Supplies

Parts and Supplies

Part VBatt 5V 3.3V 2.5V 1.8V 1.2V
FPGA
ARM
HP3 RX
HP3 TX


Battery

  • Packs need to be configured to give out 12V
  • Orientation and number need to be spec'd by both EE and ME
  • Possible on-board charger?
  • Battery health monitor
