PROBLEM TO BE SOLVED: To achieve operation with higher efficiency, in a power converter including a plurality of DC/DC converters connected in parallel with each other.SOLUTION: A power converter (12) including a first DC/DC converter (21) and a second DC/DC converter (22) connected in parallel with each other is further provided with a control section (41) for switching operation and operation stop of the second DC/DC converter, based on a current threshold that is set based on a first characteristic curve representing the relationship of the current and conversion efficiency when operating the first DC/DC converter while stopping operation of the second DC/DC converter, a second characteristic curve representing the relationship of the current and conversion efficiency when operating the first DC/DC converter and second DC/DC converter, and an input or output current in the power converter. |
