PURPOSE:To level the output currents from a plurality of power supplies to one load. CONSTITUTION:Power supplies P1, P2,..., Pn, which are operated in parallel, are provided with current transformers CT1, CT2,..., CTn, which detect the output currents, and a series circuit of resistors is connected to the secondary side of each current transformer, and each junction between resistors in series and each end are connected with one another, respectively, and the sum of voltage to the junction between resistors in series is compared with the corresponding value of the output current of each power supply Merely by providing one power supply with one current transformer, the output current of each power unit can be leveled. |
