The present invention relates to a power supply apparatus. The power supply apparatus according to the present invention comprises: a master circuit unit charging a battery at the initial stage, and supplying power to load at light load; and a slave circuit unit having a common output terminal with the master circuit unit, and supplying energy to the load by distributing and sharing the load with the master circuit unit at heavy load. Snubber capacitors capable of being charged and discharged are installed on a secondary side of each transformer of the master circuit unit and the slave circuit unit respectively. According to the present invention, power loss of a system can be reduced, and efficiency can be improved by installing snubber capacitors capable of being charged and discharged in the master circuit unit and the slave circuit unit respectively, and then supplying power to load by using energy charged to the snubber capacitors at light load. |
