Hello, I am not as familiar as I want to be on this topic and I'm looking for pointers. ;) My goal is to modify an electric cart to be charged by solar panels mounted on the cart's roof. The cart charging circuitry requires a 48 volt input and the maximum output of the solar panels (in series) is 34V and 7A. What I need then is a converter that can handle about a max of 5A output at 48 volts. In my research, I'm drawn to a boost type converter since I need a constant and higher voltage output than the input voltage. A boost converter is also attractive because of its simplicity. Designing a flyback type converter would be more difficult for me, but I want something that works well! Can anyone give me pro/con about a boost topology converter for this application? Thanks!
