Multiple Input power sources...

Hi all, I am reading up on how to pool power from various DC sources to a central charging unit. Currently, I only found a few papers on how to do this, but would like more information on how this can be done. Has anyone done this before or came across such papers or circuits? Please advise.

Thanks!!

Cheers!!

Note: I referred to one paper by Bryan G. Dobbs and Patrick L. Chapman 'A Multiple-Input DC-DC Converter Topology', but could use more information on this if possible, as well as any other helpful insights on this.
