Hi.. I am trying to imagine how a DC bus looks like physically. I have just seen DC bus as a "line"in diagrams. But in real life how does it look? Also, the voltage of a DC bus remains constant. How? Isnt it a waste of energy to have a constant supply to a DC Bus just to maintain the voltage? I am considering a PV system, a Wind turbine with rectifier and grid - all connected to a DC bus. The purpose of the DC bus is to charge a battery. Not able to imagine how it will work physically and how the use of DC bus can be justified. Any help is really appreciated. Thanks in advance!
