COUPLED INDUCTORS-BASED CHAOTIC COLPITTS OSCILLATOR

International Journal of Bifurcation and Chaos, 2011
In 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.

Coupled-inductor analysis and design

1986 17th Annual IEEE Power Electronics Specialists Conference, 1986
A 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 ...

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).

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.

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.

Variable Switching Frequency PWM Strategy for High-Frequency Circulating Current Control in Paralleled Inverters With Coupled Inductors

IEEE transactions on power electronics, 2020
Determination of high-frequency circulating current is important for coupled inductor design of paralleled voltage source inverters (VSIs). A time-domain model describing the circulating current of coupled inductor within a switching period is presented ...

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.
