Abstract
Provided is a power supply system in which two or more power supply units are optionally connected and used in any operation mode. The present invention includes a power supply main circuitthat converts AC powerinto DC power; a current detection unitthat detects an output current Io; a voltage detection unitthat detects an output voltage Vo; a parameter storage unitthat rewritably holds, as a target value Cr, operation mode information Cm selectively indicating constant current operation or constant voltage operation, and one of a target current Iref and a target voltage Vref corresponding to the operation mode information Cm; a control unitthat controls the power supply main circuitsuch that one of the output current Io and the output voltage Vo corresponding to operation mode information Cm matches the target value Cr; a balance information transmission unitthat transmits the other of the output current Io and the output voltage Vo as balance information Bi; and a balance information reception unitthat receives, as balance information Bi, the other of the output current Io and the output voltage Vo from another one of the power supply units, in which the control unitcontrols the power supply main circuitbased on balance information Bi of the own unit and of the another power supply unit and performs balance adjustment with the another power supply unit.
