PROBLEM TO BE SOLVED: To maintain bus voltage at a desired value or in a desired range by controlling an operation condition of a plurality of master legs.SOLUTION: A power router 100 includes a control part 10, a direct current bus 11, a first master leg ML1, a second master leg ML2 and a third master leg ML3. A direct current is caused to flow in the direct current bus 11. The first master leg ML1, the second master leg ML2 and the third master leg ML3 are connected to the direct current bus 11, and also perform power transmission/reception with the outside. The control part 10 controls the first master leg ML1, the second master leg ML2 and the third mater leg ML3 such that the voltage of the direct current bus 11 falls within a prescribed range. The control part 10 starts to operate a master leg other than an operating master leg in accordance with bus voltage Vm while one or more master legs operate among the first master leg ML1, the second master leg ML2 and the third master leg ML3.SELECTED DRAWING: Figure 1 |
