Rational Tuning of Hygroscopic Oscillation of Stacked Nanoflake Assemblies for Continuous Ambient Energy Harvesting

open access: yesAdvanced Materials, EarlyView.
Stacked nanoflake assembly (SNA) membranes can oscillate autonomously, offering opportunities for soft actuation and energy harvesting. This work uncovers the physical mechanism behind the sustained oscillation of SNA membranes in gradient humidity and identifies three governing dimensionless parameters, enabling rational design for optimizing SNA ...

Evaluation of Coupled Inductor Voltage Regulators

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.

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 ...

Investigation of MMIC inductor coupling effects

1997 IEEE MTT-S International Microwave Symposium Digest, 1997
The coupling effects of two closely placed coplanar spiral inductors are investigated using the FDTD method. Different configurations of two inductors are simulated and the simulation results are compared with measurements. The investigations show an unexpected high impact of the orientation of the coils to the coupling of the two inductors.

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.

Switched-coupled-inductor inverter

2013 IEEE Energy Conversion Congress and Exposition, 2013
A 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, 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 ...
