PROBLEM TO BE SOLVED: To provide power conversion equipment in which a battery capable of recovering regenerative electric power can be appropriately selected.SOLUTION: When a voltage of a regenerative electric power that is input from a first port connected with a primary side full bridge circuit is defined as VR, a discharge final voltage of a first battery connected with a center tap at a primary side of a transformer is defined as VCd, a charging final voltage of the first battery is defined as VCc, a discharge final voltage of a second battery connected with a third port connected with a secondary side full bridge circuit is defined as VBd, a charging final voltage of the second battery is defined as VBc, and a lower limit value of a duty ratio of the primary side full bridge circuit is defined as Dmin, the power conversion equipment determines that there is probability that the first battery and the second battery can be charged with the regenerative electric power when (VBd/N)≤VR≤(VBc/N) is satisfied. The power conversion equipment determines, on the other hand, that there is probability that the first battery can be charged with the regenerative electric power when VCd≤VR≤(VCc/Dmin) is satisfied. |
