Abstract - This paper presents the modelling and simulation of an autonomous DC microgrid in Matlab Simulink. A DC-DC converter, an inverter, a solar PV array, and DC loads are all included in the proposed microgrid system. The single-phase source is coupled to a single-phase PFC boost converter, which enhances the input PF utilizing two feedback loops: outer voltage loop control and inner current loop. . This can be overcome by adding a boost converter with the MPPT control algorithm, which maintains the required DC voltage level for the AC grid inverter. Such a solution is preferred because of the continuous character of the input current., renew-able energy integration, transportation electrification, energy storage, and power supplies for computing. The topology which is being brought forward is used to connect a single-phase renewable energy resource to the grid.
