ABSTRACT

Power from a wall socket may suffer abnormalities such as blackout, surge and noise. In worst case, the abnormalities condition of power supply can course loss of data in computer system or damage to electronic equipment. It is the function of Uninterruptible Power Supplies (UPS) to act as a buffer and provide clean, reliable power to valuable electronic equipment. The basic concept of UPS is to storage energy during normal operation (through battery charging) and release energy (through OC to AC conversion) during a power failure. Normally, UPS systems consist a combination of complex circuits such as battery charger, rectifier, power factor correction, battery boost, free running chopper, input power protection and inverter. This project will focus on developing single phase PWM inverter circuits. The inverter circuits consist a gate drive circuits and PWM circuit generator.
