I am trying to design a DC microgrid with solar panels and a connection to the main grid. The DC grid will have 400V on its bus. So I need to have a SOlar array with MPPT controlled DC-DC converter and then another converter outputting 400V to the DC bus. Can anyone give me some suggestions on how I can make this in Simulink and if my idea is actually on the right track.I understand how MPPt works, but connecting it to a second Converter to have a constant DC output makes it confusing. Also I am having difficulties choosing the right components inductances and capacitors, I can't find ready topologies for this.
