Beschreibung
Zusammenfassung:	A power supply system includes multiple power supply devices (1) including a first power supply device and a second power supply device that are connected in common to a load (2). The first power supply device (1) calculates control information for controlling voltage or current to be output to the load (2) and controls the output to the load (2) based on the calculated control information while transmitting the control information to the second power supply device (1). The second power supply device (1) receives the control information and controls the output to the load (2) based on the received control information while detecting current to be output from its own device to the load (2) and transmitting current information to the first power supply device (1). The first power supply device (1) receives the current information transmitted from the second power supply device (1) and calculates control information based on the received current information and the current and voltage detected by its own device.
