PROBLEM TO BE SOLVED: To provide a power supply device that can suppress variation of a DC link voltage V.SOLUTION: A bidirectional DC/DC converter 110 is configured to bidirectionally deliver energy between a primary side and a secondary side. A converter controller 130 controls the bidirectional DC/DC converter 110. A feedback controller 140 generates a feedback value Dwhose value is adjusted so that a DC link voltage Voccurring in a DC bus approaches to a predetermined target voltage V. A feedforward part 142 superimposes a feedforward value Dreflecting load current Iflowing in a load on the feedback value Dto generate a duty instruction value S4 for instructing the duty ratio of the bidirectional DC/DC converter 110.SELECTED DRAWING: Figure 3 |
