Abstract
A power supply device includes a power supply circuit configured to generate a direct current output voltage to be applied to both ends of a plurality of loads serially coupled, a detection circuit configured to detect an anomaly of a load voltage applied to each of the plurality of loads, and an adjustment circuit configured to decrease the output voltage in accordance with a number of abnormal loads where the anomaly is detected among the plurality of loads.

A power supply device comprising:
- a power supply circuit configured to generate a direct current output voltage to be applied to both ends of a plurality of loads serially coupled;
- a detection circuit configured to detect an anomaly of a load voltage applied to each of the plurality of loads;
- an adjustment circuit configured to adjust the output voltage;
- and
- a plurality of switches each coupled in parallel to a load of the plurality of loads,
- wherein, after the switch coupled in parallel to an abnormal load where an abnormal increase of the load voltage is detected among the plurality of loads is turned on, when an abnormal decrease of the load voltage of the abnormal load is detected, the adjustment circuit decreases the output voltage.
