Simulation and Experimentation of Fourth Order DC-DC Boost Converter for Renewable Energy Source Applications

In this paper, analysis and experimentation of a fourth order boost converter has been proposed for renewable energy source applications such as solar power. The output of proposed converter is fed to motor load of 220W. The main advantages of this converter are negligible current ripples at both source and load side and higher efficiency as compared to the conventional boost converter. The energy storage elements in circuit are designed and optimized using Bacterial Foraging Optimization Algorithm (BFOA) to solve the contradictory problems of steady state and dynamic performance of the system. The up-down glitch in control to output transfer function of system is reduced with the optimized values of energy storage elements in the proposed converter. Therefore dynamic response of system is analyzed with the designed values of inductor and capacitor. Closed loop control is introduced in the proposed system using proportional integral controller to maintain the output voltage constant when there is any load disturbance in the output side and wide variations in the input voltage. Simulation and hardware results of the proposed converter with input voltage of 60V and switching frequency of 100 kHz are presented.
