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

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.

Coupled-Inductor L-Source Inverter

IEEE Journal of Emerging and Selected Topics in Power Electronics, 2017
Coupled-inductor L-source inverter is proposed in this paper. Compared to other existing impedance source inverters, the proposed inverter has a unique advantage that makes the proposed inverter flexibly work in two current modes: continuous conduction mode (CCM) and discontinuous conduction mode (DCM).

Automatic tuning of coupled inductor filters

2002 IEEE 33rd Annual IEEE Power Electronics Specialists Conference. Proceedings (Cat. No.02CH37289), 2003
A coupled inductor filter is presented with interesting notch mode filtering characteristics. Although this configuration has been long established, it has received little attention. The new contribution of this paper is to provide an automatic tuning process that can make use of the frequency domain characteristics of the coupled inductor building ...

Coupling inductor models for EMI filters

2009 35th Annual Conference of IEEE Industrial Electronics, 2009
This paper analyzes the electrical parameters of differential-mode (DM) and common-mode (CM) inductors used in EMI filters. To design an EMI filter, it is necessary to identify the various parameters of the passive elements: inductors and capacitors. Because of their major impact on filter efficiency, these elements must be identified with accuracy. In

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.

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.

Evaluation of coupled inductor Voltage Regulators

2008 Twenty-Third Annual IEEE Applied Power Electronics Conference and Exposition, 2008
Usually for a CPU voltage regulator (VR), there are several different coupled inductor VR setups to improve the CPU VR performance. For example, there are three different coupled inductor VR setups for a 6 phase CPU VR: 3*2 phase coupled inductor VR, 2*3 phase coupled inductor VR and 1*6 phase coupled inductor VR.

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.

A novel coupled inductor for interleaved converters

2010 Twenty-Fifth Annual IEEE Applied Power Electronics Conference and Exposition (APEC), 2010
Aiming to reduce the volume and weight further, a novel coupled inductor is proposed in this paper. The implementation approaches and the operation principles are analyzed in detail along with the comparison analysis with three-leg coupled inductor.
