Abstract
The present disclosure relates to a load sharing system having a plurality of power supplies for powering a plurality of corresponding loads. Each one of the power supplies is associated with at least one of the loads. A power bus is also provided. A plurality of inductors is connected to the power bus. Each one of the inductors is further connected to at least one of the loads and to at least one of the power supplies, such that each adjacent pair of the inductors is connected in parallel relative to at least one of the loads. Each of the inductors has an inductance value sufficient so that if a fault develops on the power bus it serves to isolate the power supplies from the power bus. The inductance value further is such that if any one of the power supplies fails, the specific pair of inductors coupled in parallel to the load associated with the failed power supply allows the load to draw power over the power bus from other ones of the power supplies through the specific pair of inductors.
