摘要： An information handling system power supply system has a plurality of power supply units (PSUs) with outputs connected in parallel and a current balancing circuit for equalizing current from these outputs. A pseudo output current value may be added to the actual output current value for each PSU so that the parallel load sharing current balance system thinks all of the PSUs are sharing the load equally. This allows simple and inexpensive paralleling of differently rated PSUs without complex load sharing circuitry. Also, PSU stress factors may be easily compensated. For each PSU there may be a first voltage, VS1, generated that is proportional to the output current of the respective PSU. A pseudo current bias voltage, VIbais, is added to the first voltage, VS1, to produce a biased second voltage, VS2, (VS2=VS1+VIbais). The biased second voltage, VS2, now represents the apparent current output of the respective PSU when current load balancing each PSU of the power supply system. A standard current balance circuit may now balance all of the PSUs for what it thinks are equal output currents from each of the parallel connected PSUs.

摘要： An information handling system having a modular DC-DC standby power converter with programmable sequencing. The modular DC-DC standby power converter comprises a plurality of DC inputs and a plurality of DC outputs. The modular DC-DC standby power converter may also be bypassed and/or put into an off-state such that a voltage(s) of at least one output of the converter may then be the same voltage(s) of at least one input. When the modular DC-DC standby power converter is bypassed and/or in the off-state, its outputs may be at a high impedance. The output voltage(s) may be adjusted for specific system requirements. Turn-on and turn-off sequencing of the output voltage(s) may be programmed. The modular DC-DC standby power converter may have short circuit protection.

摘要： An information handling system having a power supply with automatic adjustment of over current protection for both normal and degraded modes of standby operation. A first over current protection shutdown value is used when the power supply cooling fan is operational and a second over current protection shutdown value is used when the power supply cooling fan is not operational. A fan fault detector selects between the first and second over current protection shutdown values.
