摘要：

The novel single-phase Cuk and Sepic power factor correction converter attracted toward arc welding application is highlighted in this scope. The preferred converter is outlined to function in DCM concealed by variations in load voltage and supply voltage to ensure better performance. The control strategy includes a voltage loop, which ensures arc welding process stability and improved input power quality. The designed system is validated with a hardware prototype of 100 W, 48 V, and Matlab/Simulink is used to simulate the arc welding power supply under different working conditions. The reduced input line total harmonic distortion of 1.527% with unity power factor is attained for the rated load in the investigational study. The experimental performance of the propounded converter is bestowed with operating conditions of AC mains (90-270 V) to cohere to the limits delineated by the IEC61000-3-2 standards.
