An uninterruptible power supply, commonly called a UPS is a device that has the ability to convert and control direct current (DC) energy to alternating current (AC) energy. It uses a conventional battery of 12V rating as the input source and by the action of the inverter circuitry, it produces an alternating voltage which is sent to the load. This particular UPS is designed for a small scale load like a personal computer and hence only a basic power rate is generated by the UPS. Standard Untint eruptible Power Supply (UPS) systems are connected in series between the ac mains and the critical load. A phase controlled rectifier feeds a battery-supported dc bus and an inverter supplies the load. These systems require two conversion stages. Input power factor is poor and large harmonic currents are injected into the ac mains. The proposed model will acknowledges the person from upcoming faults and suggest its remedy via SMS. If possible apply the remedy steps and avoid the fault.
