Modifiable DC-DC power converters for providing different output voltages

A method for adjusting an output voltage of a DC-DC power converter including a plurality of DC inputs configured to couple to one another to form a power converter input, a plurality of outputs configured to couple to one another to form a power converter output, and a plurality of transformers, each transformer including two or more primary windings for coupling to one input of the plurality of DC inputs and at least one secondary winding for coupling to one output of the plurality of outputs, the method comprising:

• directly connecting a first set of a plurality of input connectors between the two or more primary windings of said each transformer, connecting the first set of the plurality of input connectors between the plurality of DC inputs for providing DC power from the plurality of DC inputs to said each transformer, and connecting an output connector of a plurality of output connectors between the plurality of transformers and the plurality of outputs to provide at the power converter output a first output voltage;
• and
• directly connecting a second set of the plurality of input connectors between the two or more primary windings of said each transformer, connecting the second set of the plurality of input connectors between the plurality of DC inputs for providing DC power from the plurality of DC inputs to said each transformer, and connecting another output connector of the plurality of output connectors between the plurality of transformers and the plurality of outputs to provide at the power converter output a second output voltage different than the first output voltage;
• wherein the input connectors are each configured to change at least one of a connection between each of the two or more primary windings to adjust a turns ratio of said each transformer and a connection between the plurality of DC inputs, wherein the output connectors are each configured to change a connection between the plurality of outputs, wherein when the connection between the plurality of DC inputs is a parallel connection, the connection between the plurality of outputs is a series connection, and wherein when the connection between the plurality of DC inputs is a series connection, the connection between the plurality of outputs is a parallel connection.
