The PFC stage is an analogue solution; MCU is used to communicate with DSP chip on secondary side. on the output ensures no reverse load current and hence it is ideally suited for operation in redundant power systems. controllers. It is protected with an active OR-ing device for maximum reliability. I2C bus. The I2C bus allows full monitoring of the supply, including input and output voltage, current, power, and inside temperatures. power demand and supply temperature and can be overridden through the I2C bus.

6.10 CURRENT SHARING

All outputs shall be capable of operating in a redundant current share mode. A maximum of 6 power supplies may be operated in parallel. All outputs shall incorporate an isolation device (Or-ing MOSFET or diode) for fault isolation. Filter capacitors that are located after the isolation device shall be of high reliability and shall be de-rated sufficiently to minimize failures. The 3.3 V output current sharing shall be of a droop type. The +12 V current sharing shall be a single wire type, active curr ent sharing. Connecting the Ishare (current share) pins of each power supply together shall enable the current share feature. Shorting or opening of a current share pin shall not cause the output voltage to go out of steady state regulation. For 12 V output the Ishare (load sharing) voltage shall be a linear function Ishare [V] = 8 x Iout/108 (with 8 V at 108 A) for a single power supply (~74 mV/A). At light load, the load share becomes difficult because of low feedback signal. Refer to Table 2 for current sharing accuracy. The current balance accuracy is calculated as: 2*|I1 -I2|/ (I1+I2), where the I1 is the PSU1 load current and I2 is the PSU2 load current.

6.11 REMOTE SENSE

The outputs specified shall incorporate remote sense and will compensate for specified load cable drop. In the event of loss of remote sense, all outputs shall revert to internal sense so as to limit the outputs to less than 105% of nominal.
