<P>PROBLEM TO BE SOLVED: To prevent the expansion of damage to a normal power circuit when a fault occurs in one power circuit, in a power unit or electronic equipment using a power system where a plurality of power circuits are connected in parallel. <P>SOLUTION: The purpose is achieved by so constituting it as to provide power circuits connected in parallel with signals to output the abnormal state of a power source and to stop other power circuits connected in parallel by the signal. As a result, in case that at least one of power circuits connected in parallel gets in an abnormal state, the abnormal power circuit stops its own power circuit, and other power circuits stops their several power circuits by the signal of the abnormal power source. As a result, it can obstruct the phenomena of occurrence of an accident such as a reverse current, and can prevent the expansion of the accident. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
