1. A partial power DC-DC converter with controllable topology, CHARACTERIZED in that it comprises:
a galvanically isolated DC-DC converter having a positive input, a negative input, a positive output, and a negative output;
a first DC voltage input electrically connected to said positive input of said DC-DC converter;
an input reference;
a first DC voltage output electrically connected to said positive output of said DC-DC converter; and
an output reference electrically connected to said input reference;
wherein said partial power DC-DC converter additionally comprises:
a first switch arranged to selectively connect said positive input to said negative output of said DC-DC converter;
a second switch arranged to selectively connect said negative input of said DC-DC converter to said input reference;
a third switch arranged to selectively connect said negative output of said DC-DC converter to said output reference; and
a fourth switch arranged to selectively connect said positive output to said negative input of said DC-DC converter.
