Coupled Inductors and their Applications

2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE, 2019
This article describes the topic of coupled inductors and their EMC advantages when used in switching power supplies. It is explained how a coupled inductor works, which advantages and disadvantages it has and how it can be applied in principle. Furthermore, various DC-DC converter topologies with coupled inductors are explained and a practical example

An SIMO Step-Down Converter with Coupled Inductor

2020 International Symposium on VLSI Design, Automation and Test (VLSI-DAT), 2020
Power management IC have been widely used, and due to the development of the process, the number of transistors on the same area has grown, resulting in more sets of output requirements. The single-inductor multi-output power converter not only meets the requirements of multiple sets of voltages today, but also greatly reduces the area and cost of the ...

Modeling a Coupled-Inductor Boost Converter in the Complementarity Framework

2012 Sixth UKSim/AMSS European Symposium on Computer Modeling and Simulation, 2012
We consider the modeling of switching circuits, consisting of passive elements, independent sources, which are subject both to externally induced switches (time events) and to state events. We focus on the use of the complementarity formalism for obtaining such hybrid (actually piecewise linear) models, assuming idealized current- voltage ...

Analysis of the Interleaved Isolated Boost Converter With Coupled Inductors

IEEE Transactions on Industrial Electronics, 2015
This paper analyzes the interleaved boost with coupled inductors (IBCI) converter, which is an isolated topology that is suitable for high step-up applications. Two main contributions are given: an exhaustive steady-state analysis and an accurate small-signal model.

Coupled-inductor rectification and cycloconversion

APEC '88 Third Annual IEEE Applied Power Electronics Conference and Exposition, 1988
AC-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, 1991
The 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, 2014
This 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, 1984
A 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

1986
A 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
