Abstract: PROBLEM TO BE SOLVED: To ensure safety of a load circuit in an overload condition, by interrupting supply of a current to a load when an output current is increased up to a trigger current or more in a photo-thyristor coupler. SOLUTION: In an input power source 1, voltage chopped by a switching FET2 is applied to a primary side winding of a switching transformer 3, transmitted to a secondary side winding, smoothed to be rectified by a rectification smoothing circuit 4, and supplied to a load 5.
