1. A system, comprising:
a first polyphase regulator, comprising:
a first magnetic element,
n switching poles, n being an integer greater than 2,
a first port having a first node and a second node, and
a second port having a first node and a second node;
an alternating current to direct current (AC to DC) converter,
a transformer connected to an input of the AC to DC converter, and
a second polyphase regulator, configured to receive power from a secondary side of the transformer,
wherein:
the first magnetic element comprises n phase ports and an averaging port;
each of the n switching poles includes a phase node; and
the first polyphase regulator and the second polyphase regulator are not galvanically isolated from each other.
