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.

Reduction of proximity losses in coupled inductors
IEE Proceedings B Electric Power Applications, 1991The authors present an investigation into the leakage fields and eddy current losses in the windings of inductors and coupled inductors used in high frequency applications. They show that the eddy current losses in the windings can be reduced significantly by the use of distributed airgaps, and that under these conditions the leakage fields are ...

Predicting magnetic coupling of power inductors
2014 International Symposium on Electromagnetic Compatibility, 2014This paper proposes a new method to indirectly consider the magnetic material of rod core coils for Partial Element Equivalent Circuit (PEEC) simulations by adapting the number of turns. This way of modeling can be extended to the coupling effects in Common Mode (CM) chokes caused by Differential Mode (DM) currents passing through them.

DC chopper with coupled-inductor commutation
International Journal of Electronics, 1984A novel coupled-inductor commutation circuit is described. The circuit may also be used for inverters. It uses only two auxiliary thyristors, each operating in alternate cycles and eliminating the need for reversal of the commutating capacitor voltage. Trapped energy is fed back to the source.

Coupled-Inductor Inversion, Rectification and Cycloconversion
1986A new PWM approach using three state switching of negatively coupled inductors can be applied to any basic dc-to-dc converter to form single-phase dc-to-ac inverters. Current reference programming gives improvements in linearity, small-signal dynamics, and pulsed-load response. The current programming loops of the flyback and boost inverters are stable

Modeling and design of transformers and coupled inductors
Proceedings Eighth Annual Applied Power Electronics Conference and Exposition,, 2002The modeling and design of transformers and coupled inductors are discussed. After a brief review of Maxwell's laws and magnetic circuit models, the magnetic and electric models of transformers and coupled inductors are developed, including both magnetizing and leakage effects.
