PROBLEM TO BE SOLVED: To improve stability in DC link voltage.SOLUTION: A converter controller 106 controls a step up/down converter including a reactor and a switching element. A linear control section 330 performs feedback control of the step up/down converter so that DC link voltage Vgenerated in a DC link bus can be closer to a target level V. A non-linear control section 340 estimates an internal resistance Rof a power storage device, and on the basis of the estimated internal resistance R, adaptively changes a control parameter of the linear control section 330.SELECTED DRAWING: Figure 4 |
