Zusammenfassung:An object of the present invention is to enable two or more power supply units constituting a power supply system to be synchronized to stably operate the power supply system. A power supply system 100 includes two or more power supply units 10 to 13, the power supply units 10 to 13 cooperating to supply DC power to a shared load 22, the power supply units 10 to 13 including a power supply main circuit 30 that converts AC power inputted from the outside into DC power; a control unit 36 that controls the power supply main circuit 30; a pair of synchronous terminals Z1, Z2 respectively connected to a pair of synchronous signal lines ZCL; a transmission unit 35 that outputs a trigger signal TG by establishing conduction between the pair of synchronous signal lines ZCL; and a reception unit 35 that detects a conductive state between the pair of synchronous signal lines ZCL and that receives the trigger signal TG, wherein the power supply main circuit 30 stops outputting based on timing of receiving the trigger signal TG.
