PROBLEM TO BE SOLVED: To suppress transverse currents by independently controlling a plurality of power supplies that are connected in parallel, and to maintain voltage control by preventing the stop of the voltage control of the power supplies by the generation of transverse currents.;SOLUTION: In controlling a plurality of the power supplies connected in parallel, the independent control of the power supplies is performed by obtaining active currents and reactive ones from the output currents of the power supplies, and by performing output voltage controls including a phase control based on the active currents and a voltage amplitude control based on the reactive current. The output voltages are controlled by the voltage amplitude control so as to compensate voltage drops caused by the interior impedance of the power supplies. Each power supply performs each process independently from other power supplies. The transverse currents are suppressed in each power supply by independently compensating the voltage drop by the interior impedance, and voltage differences between the power supplies are reduced by controlling the transverse currents. As a result, the voltage of each power supply can be controlled within a preset range, so that such a case can be avoided that the voltage control is stopped by a voltage limiter that limits a large voltage difference.;COPYRIGHT: (C)2006,JPO&NCIPI
