Design Simulation and Performance Analysis of a Modified Voltage Regulator under Distorted Supply Conditions

Abstract

Reliable and stable voltage regulation is essential for the smooth operation of modern electronic and biomedical systems. While conventional voltage regulators are typically designed to perform well under ideal supply conditions, real-world power sources are rarely perfect. They often exhibit quality issues such as harmonics, voltage sags, surges, and various forms of electrical noise. These disturbances can impair regulator performance, leading to unwanted voltage variations and possible system instability. newline
