Design Drivers

• SUPPLY DESIGNED TO RBSP_EFW_LVPS_001• INPUT IS 28 VOLT POWER (22-35 VOLTS NOMINAL)• PRIMARIES ARE CURRENT LIMITED• SUPPLIES SYNCHRONIZED TO 799KHZ• FLOATING SUPLIES RUN AT 399.5KHZ, OTHERS AT 199.75KHZ • SUPPLY IS SOFT STARTED TO MINIMIZE TURN-ON STRESSES

– INPUT CURRENT CONTROLLED• REGULATION – 1% ON DIRECTLY REGULATED VOLTAGES

AND 5% ON AUXILLARY VOLTAGES• ISOLATED SECONDARIES• BEB OUTPUTS INDEPENDENT OF IDPU OUTPUTS 225V SUPPLY AND FLOATING 15V SUPPLIES FILTERED

TO 14μV RMS 10Hz-10KHz, AND 0.4μV RMS 10KHz-100KHz

PEER REVIEW RFAs

TITLE DESCRIPTION RESPONSE

Stress Analysis Ensure stress analysis done on all boards by CDR Parts chosen at design to accommodate stress margins

PCB Switch Dissipation Look at thermal dissipation of FET switches on PCB, is heat sinking necessary?

No additional heat sinking is necessary. Two of the higher dissipation FETS have new part numbers and the temp rise of the highest is less than 3°C.

LVPS Thermal Vacuum Test Check hot and cold operation of LVPS in Thermal Vacuum, in particular sync operation, soft start, in rush times, 1526 startup, floater and 225 supply outputs. Verify at hot that parts do not exceed rated temperatures.

Post CDR on complete ETU

Measure LVPS Efficiency Measure efficiency of all supplies Total efficiency of supplies is presently ~ 50%

Measure LVPS Cross Regulation

Verify that cross regulation of supplies meets 5% goal Will test asap, perhaps on new ETU (post CDR)

LVPS Free-run Frequency Verify that free run frequency of 1526 does not go above 90% of sync frequency

Currently, set point is 95% of sync frequency.

LVPS Soft start capacitors Include soft start capacitors in schematics Will be included where needed

Implement temporary current limiting on IDPU supply

Allow high inrush on the IDPU supply, but safe instrument in case of short

To be implemented with timed increase of overcurrent threshold on new ETU (post CDR).
