CURRENT-BALANCING POWER SUPPLYING DEVICE

A current-balancing power supplying device includes a master power supply and a slave power supply coupled thereto. The master power supply and the slave power supply are coupled to a load. The master power supply provides a master output current for the load, retrieves the master output current, and generates a master feedback current based on the master output current. The slave power supply receives the master feedback current, provides a slave output current equal to the master output current for the load based on the master feedback current, retrieves the slave output current, generates a slave feedback current and a slave analog current based on the slave output current, adds the master feedback current to the slave feedback current to generate a control current, and stabilizes the slave output current based on the control current and the slave analog current.
