Power converter with multi-tapped autotransformer

An apparatus comprising:

• an autotransformer including primary windings and a secondary winding;
• multiple switches including a first switch, a second switch, a third switch, and a fourth switch;
• multiple nodes including:
• i) a first node directly coupling the first switch and the second switch in series, and ii) a second node directly coupling the third switch and the fourth switch in series;
• wherein the secondary winding is connected between the first node and the second node;
• and
• an output node operative to output an output current based on:
• i) first output current supplied from the first node directly through the first switch to the output node, and ii) second output current supplied from the second node directly through the third switch to the output node.

An apparatus comprising:

• an autotransformer including multiple windings;
• first switches coupled between an input node and an output node;
• second switches coupled between a reference potential node and the output node, the reference potential node supplying a reference potential;
• wherein the first switches are operable to control switching of circuit paths including the multiple windings of the autotransformer;
• wherein the second switches are operable to convey currents received from the multiple windings of the autotransformer through the second switches to the output node;
• wherein the currents received from the multiple windings include a first current and a second current;
• wherein the multiple transformer windings include a first winding, a second winding, and a third winding;
• wherein a first node directly couples the second winding to the first winding;
• wherein a second node directly couples the third winding to the second winding;
• and
• wherein the second switches include a first switch and a second switch, the first switch operable to control flow of the first current from the first node through the first switch to the output node, the second switch operable to control flow of the second current from the second node through the second switch to the output node.
