As part of my senior design project, I need to be able to switch between two 12V, ~90A sources as an input to a large 1100W inveter. I'm planning on using a 93000uF 40VDC capacitor to support the load during the brief switchover time.
What method of switching should I use? Mechanical relay, solid state relay, MOSFET, etc? I need to switch a large amount of current at 12VDC as quickly as possible. What about using a make-before-break configuration?
The two sources will be a large battery bank charged by wind and solar, and a gas turbine generator.
