Abstract: PURPOSE: A switching mode power supply apparatus for restraining an induction noise is provided to reduce a noise of a switching power supply by changing a switching mode control frequency according to a set average value based on a rectified frequency. CONSTITUTION: A bridge diode(BD) rectifies an input alternating current power supply to a direct current power supply. A transformer(T) induces a voltage to a secondary winding when a current flows. A MOS transistor(FET) performs an on/off operation according to a PWM pulse signal applied to a gate thereof and forms a current flow passage in a primary winding of the transformer(T). The first capacitor(C1) receives an alternating current voltage applied to an input alternating current terminal of the bridge diode(BD) through the first resistor(R1) and intercepts a direct current component and passes an alternating component. A transistor(Q) performs an on/off operation according to a logic state of a received signal. One terminal of a second resistor(R2) is connected to an emitter of the transistor(Q). A third resistor(R3) is connected to a collector of the transistor(Q) and other terminal of the second resistor(R2). The second capacitor(C2) is connected between a junction point of the second and third resistors(R2,R3) and a ground.
