Abstract
This work deliberates the implementation of a DC-DC converter that offers high gain. The converter is fed from solar Photo Voltaic (PV) appropriate for DC microgrid. DC microgrid has numerous benefits in rural areas where supplying power by typical AC grid is not viable. The low output obtained from solar PV is boosted into 400 V suitable for DC microgrids used for data centers. The converter is tested for line and load variations in open-loop conditions. To maintain the output voltage at 400 V, a typical proportional-integral (PI) controller is employed, and its performance is verified in MATLAB, and simulation results are presented. It can be observed that the PI controller can maintain DC link voltage in transient conditions.
