Kind Code:

A1

Abstract:

A power supply system includes a plurality of power supply devices (1) that are all connected to a load (2). A first power supply device (1) calculates control information for controlling voltage or current to be output to the load (2), controls the output to the load (2) on the basis of the calculated control information, and transmits the control information to a second power supply device (1). The second power supply device (1) receives the control information, controls the output to the load (2) on the basis of the received control information, detects current to be output to the load (2) from the second power supply device (1), and transmits 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 on the basis of the received current information, and current and voltage detected by the first power supply device (1).
