  "textContent": "A DC power feeding device includes a power feed line connected to a DC load, a first DC/DC converter provided between a solar battery and the power feed line, and a second DC/DC converter provided between a battery and the power feed line. A first controller controls the first DC/DC converter such that maximum power tracking control of the solar battery is performed in a normal state of a commercial AC power source. The first controller controls the first DC/DC converter such that the solar battery outputs a power smaller than a load power in a power failure. A second controller controls the second DC/DC converter such that the battery is charged in the normal state of the commercial AC power source. The second controller controls the second DC/DC converter such that DC voltage on the power feed line attains a reference voltage in the power failure.",
