This paper proposes a three-phase single stage power factor corrected (PFC) bridgeless modular zeta converter based switched mode power supply (SMPS) suited for welding applications demanding high current and low voltage at the output. Typically, for high-power welding applications, modular arrangement of converters is suggested to reduce the device rating and provide ease of power expandability as...
This paper focuses on the design and development of power factor corrected (PFC) interleaved canonical switching cell (I-CSC) converter-based switched mode power supply (SMPS) for arc welding. By interleaving CSC converters, input current is shared amongst them so that high reliability and efficiency is obtained for high-power applications. I-CSC converter is designed to operate in discontinuous conduction...
