A short circuit is an abnormal connection between two nodes of an electric circuit intended to be at different voltages. This results in an electric current limited only by the Thévenin equivalent resistance of the rest of the network which can cause circuit damage, overheating, fire or explosion. A common type of short circuit occurs when the positive and negative terminals of a battery are connected with a low-resistance conductor, like a wire. With a low resistance in the connection, a high current will flow, causing the delivery of a large amount of energy in a short period of time. A short circuit fault current can, within milliseconds, be thousands of times larger than the normal operating current of the system. Damage from short circuits can be reduced or prevented by employing necessary protecting devices or circuits. Short circuit protection is very important for the work concerned in any field, as there are many chances for small or heavy damage to occur, if protection is not provided. The main object is to design a short circuit protected power supply. Its function is to supply a stable voltage, to a circuit or device that must be operated within certain power supply limits. It must be in operation whenever rewuired, that is at the time of faulty conditions, this circuit will completely isolates the working deivce or ciruit from being damged.
