The series connection of input power sources may provide a further feedback mechanism in addition to feedback for regulation which enhances overall performance. As a perfecting feature of the invention, inductor-less resonant converters which are switched in an interleaved fashion may be used in the unregulated branch while substantially cancelling the characteristic large output voltage ripple thereof.application/pdfen-USPatenthttp://pimg-fpiw.uspto.gov/fdd/86/728/078/0.pdf12034229307/77363/65H02M3/1584H02M2001/0074Y02B70/1425Y10T307/6857872886
