Efficient load distribution method and energy-saving intelligent power supply system

摘要

An energy-saving power supply system capable of reducing power consumption by efficiently operating minimum power supplies is disclosed.;A power supply system according to the present invention includes a plurality of power supplies connected in parallel; Means for connecting to the plurality of power supplies to measure an energy efficiency characteristic for a load current of the power supplies; Means coupled to the measurement means for storing the measurements; Means coupled to the storage means for sequentially accumulating the stored measurements; Means for comparing the accumulation value by the accumulation means and the load current value required by the load facility, the means being connected to the accumulation means and the load facility; And control means for selecting and driving the power supplies corresponding to the accumulated measured values when the accumulated value becomes equal to or greater than the required load current value as a result of the comparison by the comparing means.;According to the present invention, it is possible to reduce the power consumption by improving the energy efficiency of the power supply system, and to reduce the load of the power supply system, thereby preventing damage and failure of the system.
