Abstract
In an electric supply device of the present invention, since a semiconductor element Tis interrupted before a drain voltage Vof the semiconductor element Tis lower than an in-phase input minimum voltage, a load circuit can be assuredly protected. Further, assuming that a first decided voltage is L-Vand a second decided voltage V, when the voltage Vbecomes 'V<L-V', a retry operation is carried out. When the number of times of 'V<L-V' reaches Ntimes, or when the number of times of “L-V<V<V” reaches Ntimes, an interrupted state of the semiconductor element Tis held to protect the load circuit. Further, when the voltage Vsuddenly drops due to an imperfect contact of a connector, a minimum value of the voltage Vis not a stable value and the interrupted state of the semiconductor Tis not held.
