Abstract:
This work focuses on the enactment of Adaptive hybrid controller with parallel multi phasing DC- DC converter intended for direct current (DC) Arc welding application. In this regard Parallel multi phasing concept applied for various types of DC- DC converter like BUCK fed BUCK, BUCK fed SEPIC and BUCK fed CUK are compared and best performed topology BUCK fed CUK is considered. The controller for proposed converter topology adapts based on the control action required with initial fuzzy controller for better dynamic changes and finial desired minimum steady state error with PI controller. 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 with adaptive hybrid controller in high current DC welding application.
