Title: Switching Mode Power Supply Which Is Durable To the Over Input Current
Inventor: LEE JEONG UK
IPC: H02M3/335
Filed: 2000-07-25
Abstract: PURPOSE: A switching mode type of power supply with over-current protection function is provided to implement a simple and efficient structure by sensing a low voltage or over-current at the output terminal of a rectifying unit, cutting off an operation power of pulse width modulation IC when the low voltage or over-current are applied. CONSTITUTION: A rectifying unit(10) rectifies and outputs an alternative current inputted thereto from an external power supply. A transformer(T1) receives a DC power provided thereto through the rectifying unit(10) from one terminal of its primary side, and outputs a voltage necessary for each part of an electric appliance to corresponding parts through its secondary side. A power transistor(Q1) is connected with the other terminal of the primary side of the transformer(T1) and switches the power supply provided to the primary side of the transformer(T1). A pulse width modulation IC(40) transmits a switching signal to a gate terminal of the power transistor(Q1), thereby controlling the operation of the power transistor(Q1). A control switch(100), which is connected with the output terminal of the rectifying unit(10), senses a voltage or current of the DC power, cuts off an operation power of the pulse width modulation IC(40) when the low voltage or over-current are applied.
