Design Uninterruptible Power Supply using a Supercapacitor as a Power Source for the Computer

Abstract

The purposes of this research were to (1) study charge and discharge a combination of supercapacitor and an AC power source in storing and supplying energy (2) find the efficiency of the supercapacitor. (3) study supplying power for a computer by a supercapacitor and (4) Determine the effectiveness of the alternator with supercapacitor power.
The results show that a renewable energy source can be reused more than 1,00,000 cycle and reduce pollution. According to the behavior of storing and supplying energy, the supercapacitor can be charged at a high current but not overvoltage while battery cannot. Voltage change becomes transient and current is constant. As charging time depends on currents, the higher current. In contrast, a low current causes longer. A supercapacitor’s efficiency in storing and supplying power by using specific high voltage and low current is high 95.20%. An analysis also revealed that charge time of super capacitor is less than 199 seconds; that of a combination of super capacitor and battery is 604 seconds and that of battery is the longest 1,080 seconds. Analysis of the discharge time used as a backup power to the computer. The study found that, discharge time of a combination of super capacitor and battery is more than 56 seconds. Discharge time of a battery and a supercapacitor are 54 and 41 seconds, respectively. The design uninterruptible power supply using supercapacitor as a power source. The supercapacitor will time to store energy faster than the battery.
