1. INTRODUCTION The rapid evolution of electronic devices and systems has led to increasing demand for efficient and precise power delivery solutions. Traditional linear power supplies and even early switching power supplies have been effective to some extent, but they often lack the necessary flexibility and precision to meet the dynamic power requirements of modern electronic systems. Programmable DC power supplies have emerged as a viable alternative to address these limitations. By providing dynamic control over voltage, current, and other parameters, programmable power supplies offer unmatched versatility, enabling optimal power delivery to electronic devices. This paper aims to explore the development of programmable power supply technology, investigate its advantages over traditional power supplies, and present real-world applications showcasing the benefits of adopting these solutions.

1.2Description 1.2.1Rectifier with Power Factor Correction: The Rectifier used for the project is GBU806 which has been selected on many criteria considering the requirements Working Peak Reverse Voltage of 600 V and Average Forward Rectified Current 8 Amperes with surge current 200A.For Power Factor Correction Circuit a Power Factor Controller is used which is NCP1608.
1.2.2Low Drop-out Regulator: Low dropout regulators (LDOs) are a simple inexpensive way to regulate an output voltage that is powered from a higher voltage input. LDO has three main components, i.e. pass element, error amplifier, and reference voltage source. Typically a pass element is an N-channel or P-channel FET, but can also be an NPN transistor or PNP transistor.
