“…The BL-buck converter is inappropriate for arc welding power supply applications because of its limited output voltage range. In this study, the buck-boost configurations of the Sepic, Zeta, and Cuk converters were found to have higher switching losses and power losses [17][18][19][20][21][22]. In this literature, a PFC-based bridgeless Luo converterfed BLDC motor drive is mentioned in [23].…”

This research paper proposes an enhanced power quality in bridgeless modified Landsman-Canonical switching cell (BMLCSC) converter used for arc welding power supplies. This proposed converter topology is presented for circuit component reduction to eliminate the need for a diode bridge rectifier and input filter to make the circuit more compact. The proposed converter is operated on discontinuous conduction mode (DCM). A closed loop PI control circuit with a single voltage sensor is utilized to achieve load regulation, line regulation with high efficiency and quick response. The exploratory performance of preferred framework is simulated using Matlab/Simulink and validated with a hardware prototype of 100 W, 48 V.
