Coupled-inductor core for unbalanced phase currents

A method, comprising:

• driving a magnetizing first current through a first conductor and into an output node during a first period, the first conductor wrapped around a first form of a core, the magnetizing first current having a first magnitude and generating a first magnetic flux through the first form, the first form having a first characteristic of a first value, a density of the first magnetic flux flowing through the form depending on the characteristic;
• and
• directing a first portion of the first magnetic flux through a second form of the core, the first portion of the flux causing an induced second current to flow through a second conductor and into the output node, the second conductor wrapped around the second form of the core, the induced second current having a second magnitude, the second form having the characteristic of a second value that is different from the first value.

A method, comprising:

• driving a magnetizing first current having a first magnitude through a first winding and into an output node during a first period, the first winding having a number of turns;
• and
• driving a magnetizing second current having a second magnitude through a second winding and into the output node during a second period, the second winding having the number of turns and being magnetically coupled to the first winding.
