COUPLED INDUCTORS-BASED CHAOTIC COLPITTS OSCILLATOR
International Journal of Bifurcation and Chaos, 2011In this paper, a new chaotic circuit is introduced, conceived by considering a Colpitts oscillator with the inclusion of two further elements: a coupled inductor and a variable resistor. The proposed circuit exhibits a rich dynamics that has been experimentally characterized through the bifurcation diagram with respect to the resistor value.

Switched-coupled-inductor inverter
2013 IEEE Energy Conversion Congress and Exposition, 2013A new family of switched-coupled-inductor inverters has been proposed in this paper, with voltage buck-boost function. In voltage-fed switched-coupled-inductor inverter, a boost function can be implemented by introducing an extra shoot-through state on the inverter bridge.

Coupled-inductor analysis and design
1986 17th Annual IEEE Power Electronics Specialists Conference, 1986A new coupled-inductor multiple air-gap structure is proposed and analyzed. These EI and EE core configurations eliminate many of the problems associated with the earlier single air-gap structures such as: high sensitivity of ripple currents to air-gap and/or turns ratio changes, complex winding arrangements and consequent high costs and inferior ...

An SIMO Step-Down Converter with Coupled Inductor
2020 International Symposium on VLSI Design, Automation and Test (VLSI-DAT), 2020Power 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 ...

Evaluation of Coupled Inductor Voltage Regulators
IEEE Applied Power Electronics Conference and Exposition, 2008Usually 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.

Coupled Inductors and their Applications
2019 International Symposium on Electromagnetic Compatibility - EMC EUROPE, 2019This 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

Modeling a Coupled-Inductor Boost Converter in the Complementarity Framework
2012 Sixth UKSim/AMSS European Symposium on Computer Modeling and Simulation, 2012We 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, 2015This 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.

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 ...

Introduction to Modeling of Transformers and Coupled Inductors
IEEE Transactions on Power Electronics, 1995A tutorial paper is presented on modeling and design of transformers and coupled inductors. Beginning with a brief review of electromagnetic laws and magnetic circuit models, the magnetic and electric models of transformers and coupled inductors are developed, including both magnetizing and leakage effects.
