Multiple‐input DC/DC converter topology for hybrid energy system

Abstract

In this study, a multiple‐input non‐isolated DC/DC converter topology is presented. The proposed multiple‐input DC/DC converter is proficient for energy diversification from renewable and storage energy sources individually or simultaneously. It can be operated in buck, boost and buck–boost modes of operation with the capability of bidirectional power flow to achieve desired voltage level on either side. The development of small‐signal modelling based on state‐space averaging has been discussed. In addition, a power management control scheme for the proposed converter has also been presented. The proposed concept has been investigated through simulation using the MATLAB/Simulink environment and validated experimentally on a laboratory prototype using dSPACE 1103 real time digital controller.
