Document Type and Number:
Japanese Patent JP2020089197
Kind Code:
A
Abstract:
To provide a power conversion system, a control method, and a program capable of suppressing a ripple current.SOLUTION: Each of multiple converter devices 2 has a DC/DC conversion circuit 21 that DC/DC converts a DC power supplied from distributed power supplies 4 and outputs the same to an inverter device 3; and a converter control unit 22. The inverter device 3 has a connection part 35, a capacitor C3, and a DC/AC conversion circuit 31. The DC/AC conversion circuit 31 DC/AC converts the DC power input to the connection part 35 and outputs the same. An input control unit 332 outputs an instruction signal including a phase change instruction of output control of the DC/DC conversion circuit 21 to the converter control unit 22 of at least one converter device 2 out of the multiple converter devices 2.SELECTED DRAWING: Figure 1
