ABSTRACT:
Each power supply of a number of power supplies equally shares the current load supplied by the respective parallel voltage outputs of the supplies. Each power supply is identical to the others and each has the capability to operate as a stand-alone power supply, a master of a master/slave combination, or a slave of a master/slave combination. The determining factor of whether a unit is a master or a slave of a master/slave(s) combination is a single two conductor cable which has the master connection at one end and the slave connector(s) at the remaining end(s). Whichever of the otherwise identical units that the master connection is connected to will be the master unit and whichever of the units are connected to the slave connection(s) will be the slave unit(s). Thus a simple, inexpensive, interchangeable master or slave capability is provided with units which are controlled by the master to equally share the current load.
