Trans-inductor voltage regulator with nonlinear compensation inductor

Last updated:

Abstract:

A trans-inductor voltage regulator (TLVR) circuit has multiple phases and a regulator block for each phase. Each regulator block has a winding of a transformer as an output inductor. The other windings of the transformers are connected in series with a nonlinear compensation inductor. The compensation inductor has a large inductance when the compensation inductor current is responsive to a steady state load current and has a small inductance when the compensation inductor current is responsive to a transient load current.
