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 Inductors Analysis with Saturation and Thermal Effects

2020 27th IEEE International Conference on Electronics, Circuits and Systems (ICECS), 2020
This paper discusses the analysis of Coupled Inductors (CIs) in Switch-Mode Power Supplies (SMPSs), with saturation and thermal effects. A Single-Ended Primary Inductor Converter (SEPIC) topology is considered as a case study and a numerical procedure is proposed to reliably evaluate the CI windings current waveforms, including the effects of the real ...

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.

Switched-coupled inductor DC-DC converters

2018 IEEE International Conference on Industrial Electronics for Sustainable Energy Systems (IESES), 2018
In this paper, a family of high efficiency high step-up dc-dc converter is presented, which inherits all advantages of both switched-inductor dc-dc converter and coupled-inductor dc-dc converter. The proposed converters can achieve high step-up capability with the proper duty cycle D (high or small D leads to the bad efficiency), obtain soft-switching ...

Novel Coupled-Inductor Multi-phase VRs

APEC 07 - Twenty-Second Annual IEEE Applied Power Electronics Conference and Exposition, 2007
Coupling 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.

Additive Manufacturing of Hetero-Magnetic Coupled Inductors

IEEE Transactions on Components, Packaging and Manufacturing Technology, 2021
Coupled inductors are used in power electronics to improve transient response and reduce component size. To further increase inductance density and reduce fringing fields, a combination of different magnetic materials was introduced to create a hetero-magnetic coupled inductor (HMCI) core.

Litz Wire Pulsed Power Air Core Coupled Inductor

IEEE Transactions on Industry Applications, 2014
A methodology for designing high-current air core pulsed power coupled inductors is presented with emphasis on simplicity. Standard inductor design is based on derated current densities and magnetic flux densities to make the most efficient utilization of materials, but the presented pulsed power inductors have low duty cycle and are designed based on ...

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.

Coupled inductor characterization and SPICE modeling

Fifth Annual Proceedings on Applied Power Electronics Conference and Exposition, 1990
A 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. >
