Abstract
An apparatus having a first set of windings disposed about a first main leg of a transformer core, and a second set of windings disposed about a second main leg of the transformer core. The first set of windings are electrically coupled to the second set of windings to selectively provide a parallel connection and a series connection between the first set of windings and the second set of windings. Additionally, at least two windings of the first set of windings are electrically coupled to each other to selectively provide a parallel connection and a serial connection between the at least two windings of the first set of windings. Similarly, two windings of the second set of windings are electrically coupled to each other to selectively provide a parallel connection and a serial connection between the at least two windings of the second set of windings.
