Novel Coupled-Inductor Multi-phase VRs
APEC 07 - Twenty-Second Annual IEEE Applied Power Electronics Conference and Exposition, 2007Coupling the output inductors of the multi-phase Buck can reduce the steady-state current ripple while maintaining the same transient response. The conduction losses in the switches can thus be reduced. Furthermore, using coupled inductor can greatly improve the dynamic performance with smaller inductance during the transient.

Coupled-inductor rectification and cycloconversion
APEC '88 Third Annual IEEE Applied Power Electronics Conference and Exposition, 1988AC-to-DC rectifiers and polyphase AC-to-DC cycloconverters are derived from the basic DC-to-DC converters by the addition of negatively coupled inductors with a minimal number of switching devices. The circuits also use space and time-multiplexed magnetics to handle the multiple inputs and outputs.

Coupled inductor characterization and SPICE modeling
Fifth Annual Proceedings on Applied Power Electronics Conference and Exposition, 1990A complete coupled inductor characterization method, including leakage flux, is described, and its SPICE model is presented. Another SPICE model is developed for p-p ripple current determination in the windings of the coupled inductor in a switching converter and its use is extended to AC stability and audiosusceptibility analyses. >
