Modular Zigzag Converter Based Power Quality Improved SMPS for Arc Welding

This paper deals with reduction of Total Harmonic Distortion (THD) in the AC Mains by implementing the power factor corrected (PFC) ZigZag Converter for multiple output Switch Mode Power Supply (SMPS) circuit. The system consists of converting single phase supply voltage into multiple output DC voltages. In this work ZigZag converter which is DC – DC converter is operated in various modes from which best selection is done which is suitable for many industrial applications. Another converter is cascaded with Zigzag converter to convert one level of voltage into multiple levels of DC Voltages. Finally the test results are obtained in MATLAB software ZigZag converter operating in different Modes.
