Abstract
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.
