This paper presents the performance parameters of DC microgrid system using solar photovoltaic module. The solar power is fed through DC–DC boost converter, which is also equipped with MPPT to extract maximum solar energy. Boost converter connected along with PV module and Li-ion battery boosts up output voltage to the desired value, which is being fed to the DC bus. In order to obtain the highest efficiency and highest output power, MPPT is essential to drive the system till maximum power point. The voltage across DC bus is maintained to a certain desired value so that load can be applied to the circuit. Comparison and validation of DC output voltage are done by changing the load (resistive and inductive). Reduction of ripples in the DC output voltage is done by connecting inductors and capacitors in series and parallel, respectively. Three-phase AC source is also used and converted to DC by rectifier. Buffer circuits are used to handle the instantaneous power imbalance between source and load of the entire circuit. The system is modeled in the PSIM software, and the results obtained show that the ripples in resistive load are less as compared to the inductive load.
