TRANS-INDUCTOR VOLTAGE REGULATOR WITH NONLINEAR TRANSFORMER
Last updated:
Abstract:
A trans-inductor voltage regulator (TLVR) circuit has multiple phases and a regulator block for each phase. Each regulator block is connected to an output capacitor of the TLVR circuit by way of a first winding of a corresponding nonlinear transformer. A second winding of the nonlinear transformers are connected in series with a compensation inductor. The first winding of the corresponding nonlinear transformer has a first inductance when a load current is at a first level, and the first winding of the corresponding nonlinear transformer has a second inductance that is less than the first inductance when the load current is at a second level that is higher than the first level.
