Abstract

This paper presents a transformerless AC-DC converter for low-voltage applications that has a compact design, high efficiency, good power quality, and low switching losses. The recommended converter is more economical, small, and energy-efficient without a transformer stage. Stable voltage conversion rates and electrical isolation are guaranteed by sophisticated controllers. In a variety of load settings, power factor and high-frequency switching optimization enhances conversion, eliminates harmonic distortion, and stabilizes DC output. The converter functions best in low-voltage electrical systems, battery charging systems, renewable energy connections, and lightweight, energy-efficient industrial power sources. The proposed AC-DC converter architecture is efficient, reliable, and less vulnerable to electromagnetic interference, according to performance study and simulation.
