dc.description.abstract | The gap between electric power generation and demand increases newlineday by day owing to the exponential growth of power consumption. newlineEventually the power holidays and load shedding have become unavoidable in newlinedeveloping countries like ours. Power interruption leading to various newlinedevastations has been experienced and is proven to be a threat to power newlineconsumers especially in large industries. Losses in terms of life, finance and newlineproductivity are the most common aftermath of power interruption. Hence, a newlinesmart power backup and protection system has been developed. It is known as newlineUninterruptible Power Supply (UPS) that provides solutions for the power newlinesupply interruptions. UPS has become a crucial remedy for institutions like hospitals, newlineresearch laboratories, offices and even in domestic circles to ensure newlinecontinuous power supply. The primary role of any UPS is to provide short newlineterm power when the input power source fails. The improper output newlinewaveforms and harmonic injection on either ends are the major problems as newlinefor as any UPS system is concerned and need to be addressed immediately. Electrical power supply interference can come in a range of forms, newlinesuch as voltage dips, surges and harmonics or voltage spikes. These newlinedisruptions can cause serious harm to sensitive electrical equipment, newlineparticularly during the critical processing or production stages of an newlineoperation. To reduce the risk of power supply distortion, UPS systems are often incorporated in electrical networks. UPS systems provide reliable, high newlinequality power flow for sensitive electrical load equipment and are commonly newlinefound in industrial processing applications, medical facilities, emergency newlineequipment, telecommunications and computerized data systems. An UPS newlinesystem can be a helpful tool for ensuring proper power supply performance. An UPS is supposed to provide quality sinusoidal signal during newlinevoltage sag and power quality problems in AC mains of the utilities. | en_US |
