PURPOSE:To enable supplying a load with a superior quality power by judging the contents of a failure, when an apparatus is stopped after the protective detection of said failure inside said apparatus, and by operating said apparatus again to continue a power supply to said load against a failure caused by external factors where the apparatus is automatically resettable. CONSTITUTION:When the protective detection of a failure is conducted inside an apparatus to find that the continuation of operation becomes impossible, a failure detection circuit 29 detects said fact and stops the operation of said apparatus once via operation stopping circuit 27 so that a load 52 is supplied with power from other power source. Then, a failure judging circuit 57 judges whether said failure is caused by external factors of said apparatus or internal factors and, in case of a failure caused by external factors where the apparatus is automatically resettable, starts said apparatus again to continue a power supply to said load 52. |
