Abstract
A DC/DC converter which includes a first DC link, the first DC link can be a first DC link capacitor; a first plurality of N>1 converter bridges connected in parallel to the first DC link; and a transformer, the transformer can be a medium frequency transformer. The transformer includes a primary side and a secondary side, the primary side including at least one primary winding. The converter further includes a first plurality of N impedance elements, for each converter bridge, a respective impedance element of the first plurality of impedance elements is connected between the converter bridge and the at least one primary winding.
