Abstract
Coupled inductors offer advantages in terms of cost and efficiency for multiphase DC/DC converters. Using the example of a two-phase 48/12 V buck converter, the system behavior with uncoupled and coupled inductors are compared. For the same system characteristics, less material (core and winding) is required using a coupled inductor. Three approximation equations for the fringing field of the air gaps are compared by using a reluctance model. The inductor properties of the coupled and uncoupled inductors are compared with FEM simulations, small-signal and pulse measurements.
