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 ...

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.

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.

New coupled-inductors current-doubler topology

IEEE 34th Annual Conference on Power Electronics Specialist, 2003. PESC '03., 2003
Point-of-load DC-DC converters for current and next generation of ICs for communication systems and microprocessors are increasingly becoming stricter than ever. This is due to the required tight dynamic tolerances allowed for supply voltages and high dynamic performance demand coupled with very high power density.

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 ...

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.
