Trans-inductor voltage regulator using a nonlinear compensation inductor

A method comprising:

• providing at least two voltage converter phases of a trans-inductor voltage regulator (TLVR) with a common input voltage;
• coupling an output of each converter phase to a first terminal of a primary winding of an coupled inductor of the TLVR, each coupled inductor including a secondary winding magnetically coupled to the primary winding;
• for each primary winding, coupling a second terminal of the primary winding to a load;
