A workflow management apparatus 12 holds a transition condition for each stage to be switched to a next stage in a workflow that controls an operation of an external device over a plurality of stages, and stage information indicating a current stage of the workflow. Where there is a partially ordered relation between the stages, if a first and second stage are incomparable, when a third stage can be executed as a next stage of the first stage, and if the third and second stages are incomparable, when a transition condition for the first stage has been fulfilled and a transition condition for the second stage has not been fulfilled, the workflow management apparatus 12 updates the stage information so as to indicate that both the second stage and the third stage to be executed as a stage following the first stage are set for the workflow.

This power converter is provided with: three clusters (CLu, CLv, CLw) in which unit cells are cascade-connected; and power supplies of the same kind which are respectively connected to one end of each of the three clusters. Terminals of the three clusters at the side not connected to the power supplies are respectively connected to other ends of the power supplies connected to the other clusters to form a delta-connection configuration. Three connections of the delta-connection configuration are respectively connected to each of the U, V, and W phases of a three-phase alternating current, and power conversion between the power supplies and the three-phase AC is enabled. If DC power supplies (Vdcu, Vdcv, Vdcw) are employed as the power supplies, power conversion between the DC power supplies and the three-phase AC power supplies can be performed. If in-phase single-phase AC power supplies are employed as the power supplies, power conversion between either the single-phase AC power supplies and the three-phase AC power supplies, or the three-phase AC power supplies can be performed.
