Design of Analog Power Line Filter for Sensitive Equipment

Abstract

For precise and dependable operation, modern electronic systems depend heavily on a clean and steady power source. However, undesired disturbances like noise, harmonics, and electromagnetic interference are frequently present in practical power lines, which can impair the functionality of delicate equipment. In order to reduce such disruptions and enhance power quality, an analog power line filter is designed and implemented in this work. Resistors, capacitors, and operational amplifiers are among the basic analog components used to implement the suggested filter. It works by maintaining the integrity of the basic power signal while attenuating unwanted frequency components, especially those resulting from fluctuations, harmonics, and EMI. The design places a strong emphasis on practicality, affordability, and simplicity.
