Abstract

Objective: This paper presents a new DC-DC boost converter for renewable hybrid power generation scheme is designed using five controllable switches in its unified structure. Methods/ Statistical Analysis: In this research work, converter operation is discussed with four different operating modes based on the renewable resources availability. To rectify the difficulties associated with controller design of this converter, multi input - multi output controller design is obtained by deducing the small signal equations and state space modeling for all the operating modes. In this study, MATLAB/Simulink is used to design the model for DC-DC boost converter. A strategy to manage the power flow between the different energy sources is presented. Findings: Uncomplicated structure, centralized control, transformer-less operation, less weight, highly stable and increased output voltage is the best qualities of the designed converter. This study demonstrates that the overall power management is efficient and demand is balanced successfully. Applications/Improvement: This research helps to find the best power electronic converter structure for renewable based hybrid power generation system.
