PROBLEM TO BE SOLVED: To provide a power supply for industrial machinery capable of reducing power consumption.SOLUTION: A power supply 100 is loaded on an industrial vehicle which includes an electric motor 12 and an inverter 18A for driving the electric motor 12. A bidirectional DC/DC converter 110, having a capacitor 102 connected to the primary side and a DC bus 104 connected to the secondary side, is configured to be capable of exchanging energy between the primary side and the secondary side in a bidirectional manner. A converter controller 120 controls the bidirectional DC/DC converter 110 in such a manner that a DC link voltage Vgenerated at the DC bus 104 approaches a predetermined target voltage Vr. When the inverter 18A stops, the converter controller 120 stops the switching of the bidirectional DC/DC converter 110. |
