Coupled-inductor based multilevel inverter

2017 14th International Conference on Electrical Engineering/Electronics, Computer, Telecommunications and Information Technology (ECTI-CON), 2017
In this paper, a new hybrid coupled inductor multilevel inverter (HCIMLI) is proposed. The common characteristic of the coupled inductor inverters is to provide parallel paths for the output current. Therefore, the switching devices operate in lower current rate compared to the rated output current.

An Improved Current-Doubler with Coupled Inductors

2006 CES/IEEE 5th International Power Electronics and Motion Control Conference, 2006
In this paper, an improved current-doubler rectifier with coupled inductors is proposed, which can extend duty ratio to reduce the peak current through the isolation transformer and to lower output current ripple. Additionally, passive lossless snubbers are introduced to reduce reverse recovery loss and clamp the voltage spike across the rectifier ...

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. >

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

Coupled-Inductor Magnetics in Power Electronics

1987
Leakages are inseparably associated with magnetic circuits and are always thought of in three different negative ways: either you have them and you don't want them (transformers), or you don't have them but want them (to limit transformer short circuit currents), or you have them and want them, but you don't have them in the right amount (coupled ...

Modeling and design of transformers and coupled inductors

Proceedings Eighth Annual Applied Power Electronics Conference and Exposition,, 2002
The 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.

Modeling of mutual coupling between inductors

2015 IEEE Symposium on Electromagnetic Compatibility and Signal Integrity, 2015
This paper is devoted to EMI filter inductor modeling and mutual coupling modeling between two inductors positioned on PCB. 3D inductor models are developed and modeled in CST MWS. Comparison of inductors mutual coupling measurement and modeling results show that transfer coefficients can be predicted accurately.

On the energy approach to the theory of coupled inductors

European Transactions on Electrical Power, 1998
AbstractThe paper presents a revisited energy approach to the theory of a set of n coupled inductors. The hybrid constitutive relations are analyzed. It is shown that the fundamental relation expressing the energy of the system requires a minimum number of coupling terms if a set of hybrid independent variables is adopted.

Surrogate-based optimization of coupled inductors

COMPEL - The international journal for computation and mathematics in electrical and electronic engineering
Purpose The purpose of this paper is to present an application-specific optimization methodology for the design of coupled inductors used in multilevel interleaved power converters. This study focuses on minimizing core losses to meet power density requirements, reducing component volume to address cost ...
