摘要： A management or control of a power router is more appropriately performed when a power network system in which power cells are asynchronously connected with each other. A plurality of power conversion legs bi-directionally convert power, one ends thereof are connected with a direct current bus and the other ends thereof are connected with an external connection destination as an external connection terminal. A control unit controls operations of the plurality of power conversion legs. The control unit receives a control instruction including a designation of an activation target leg and a designation of an operation mode of the activation target leg. The control unit determines whether the activation target leg can be activated in a designated operation mode. The control unit activates the activation target leg in the designated operation mode when the activation target leg can be activated in the designated operation mode.

The voltage command generating unit includes an AC current control unit, a circulating current control unit, and a command distributing unit. On the basis of inputted voltage commands, the command distributing unit subtracts voltage drop portions due to inductance values in the arms from respective voltages assigned as outputs of the positive arm and the negative arm, to distribute voltage components, thereby determining the positive arm voltage command and the negative arm voltage command.
