Objective: Design an interleaving DC/DC converter system for a data center application with the following specifications: • Input voltage: 45 – 60 v• Output voltage: 3 V• Output current: 100A• Efficiency > 85% (extra credit for efficiency higher than 90% on a spice-based software simulation…

Solution: In the above CCM(40 to 50V and 400 to 500V), Boost CCM (20to -30V and 200 to -300V) and sepic (30 -60V and 300 to -600V) are chosen. Totally 6 topologies are chosen. Buck Converter: Buck converter in contious continous mode: Buck convertor does DC-DC conversion. Buck converter step down DC voltage. It consists…

In a laboratory experiment, data of voltage and current has been recorded and the same is attached in an excel file ( VI.xlsx ). Read the excel file in the Matlab program and perform the interpolation in the range of -17.3:0.1:0.9. Generate the interactive plot for the interpolated data. Additionally, compute…
