Each of the plurality of portions connected across at least two of the plurality of series connected battery cells. A first switch in series between each of the plurality of portions of the secondary side and a first battery cell of the at least two of the plurality of series connected battery cells provides a charging current to the first battery cell during a first portion of a cycle of a current in the primary side of the transformer.
