Design and Performance Evaluation of SMC-Based DC–DC Converters for Microgrid Applications

In recent times, DC microgrids (MGs) have received significant attention due to environmental concerns and the demand for clean energies. Energy storage systems (ESSs) photovoltaic (PV) are parts of MGs. This paper expands on modeling control non-isolated, non-inverting four-switch buck-boost (FSBB) synchronous converters, which interface with a wide range low-power electronic appliances. The proposed power converter can work efficiently both independently in charging discharging battery analyzed using FSBB at steady state continuous conduction mode (CCM). A boost is connected PV system, then parallel provide voltages bus. Finally, another resistive load that successfully performs boost-and-buck operation smooth transitions. Since these converters possess uncertainties non-linearities, it not suitable design linear controllers systems. Therefore, controlling mechanism converters’ based sliding (SMC). this study, various macro-level interests were achieved SMC. MATLAB Simulink results prove precise reference tracking robust stability different operating modes DC–DC MG structure.
