<p>PROBLEM TO BE SOLVED: To provide a power supply in which the output characteristics of each individual power supply can be set independently, when a plurality of power supplies are operated in parallel connection.SOLUTION: A power conversion unit 11 is controlled so that an AC current Iac inputted and outputted at terminal P1 and the voltage Vdc (voltage of a DC bus 7) at terminal P2 have a relationship defined by a predetermined function, and this predetermined function is changed depending on a control signal Sc. Consequently, the output characteristics of each individual power supply 10 can be set independently, when a plurality of power supplies 10 are operated in parallel connection.</p> |
