Abstract:
This work focuses on the design and implementation of hybrid controller for parallel DC- DC converter intended for direct current (DC) Arc welding application. In this work Parallel multi phasing Topology of DC- DC converter is considered to ensure current sharing between the converters with reduced stress. The proposed hybrid controller combines the advantages of proportional integral controller at steady state and fuzzy logic controller at transient state. A complete comprehensive simulation of proposed controller is carried out and results indicate the dynamics of proposed system is robust with sudden variations in load. Experimental studies justify the application of hybrid controller for welding applications.
