  • Power supply system with automatic transfer function and method of controlling the same
    Patent number: 8860251
    Abstract: A power supply system with an automatic transfer function includes a main-power-loop apparatus, a backup-power-loop apparatus, and a control unit. The main-power-loop apparatus has a first primary relay switch and a first SCR switch. The backup-power-loop apparatus has a second primary relay switch and a second SCR switch. The control unit turns on the first primary relay switch and the first SCR switch when a main power source can normally supply power, thus supplying power to a load via the main-power-loop apparatus by the main power source. The control unit turns on the second primary relay switch and the second SCR switch when the main power source cannot normally supply power, thus supplying power to the load via the backup-power-loop apparatus by a backup power source.
