Comparative Study of PI and One-Cycle Control of a Dual-Input DC/DC Converter

Different types of multi-input DC-DC converters have been proposed by number of researchers for the purpose of integrating more than one energy source. Development of a suitable power electronic interface is most essential for integrating these sources with very less number of components. Nowadays, it is very much essential to stabilize the output voltage of DC/DC converters in order to ensure maximum efficiency and better performance. This paper deals with the design of a suitable control strategy for multi-input DC/DC converter. To achieve this objective, two different control techniques i.e. PI and One-Cycle control have been adopted. Finally, the transient as well as steady state analysis have been done for both the control techniques with the help of MATLAB/Simulink platform and performance comparison has been performed. In order to check the feasibility of the Dual-Input DC/DC converter, a small-scale experimental prototype has been built in the laboratory environment and validations has been done using dSPACE 1104 real time digital controller.
