Abstract
PURPOSE: To prevent malfunction of the switching power source circuit while maintaining satisfactory duty service efficiency thereof by providing a protective circuit of the power source circuit with a hold circuit.
CONSTITUTION: In addition to an overcurrent detection circuit 17 a hold circuit for memorizing the output of this circuit is provided. The hole circuit is connected at its input side to the output side of the overcurrent detection circuit 17 and at its output side to the other input terminal of an AND circuit 18. Further, it is connected to a juncture between a resistor 9 and a capacitor 10 so that it can be sufficiently operated by current of charging of the capacitor 10 through the resistor 9 for starting. Thus, it holds a change at the time of occurrence of a fault to hold the switching operation stopped until the renewal of the power source. In this way, it is possible to prevent malfunction without reducing the duty service efficienty of the power source circuit and also obtain smooth starting operation of the power source circuit.
