Control of Inverter-Interfaced Distributed Generation Units for Voltage and Current Harmonics Compensation in Grid-Connected Microgrids [PDF]
Journal of Operation and Automation in Power Engineering, 2016 In this paper, a new approach is proposed for voltage and current harmonics compensation in grid-connected microgrids (MGs). If sensitive loads are connected to the point of common coupling (PCC), compensation is carried out in order to reduce PCC ...

Power computation for the triboelectric nanogenerator
, 2018 We consider, from a mathematical perspective, the power generated by a contact-mode triboelectric nanogenerator, an energy harvesting device that has been well studied recently. We encapsulate the behaviour of the device in a differential equation, which

Spin‐Orbit Torque Induced by Switchable Crystal Inversion Symmetry Breaking
Advanced Materials, EarlyView.An exotic crystal inversion symmetry breaking in SrRuO3/BiFeO3 heterostructure is revealed, and it can be reversibly manipulated by the ferroelectric polarization of BiFeO3. This crystal inversion symmetry breaking can dramatically enhance the spin‐orbit torque efficiency in the SrRuO3 layer by more than 60%, providing an alternative to design an ...

Decoupled Control of an Active Power Filter in a Vibrating Reference Frame
Power Electronics and DrivesActive power filter (APF) control is a natural area of application for vibrating reference frame (VRF) transformation due to the intentional occurrence of higher harmonics in the active filter current compensating load current harmonics.

Total harmonic current of a large number of non-linear single phase loads [PDF]
, 2002 The cumulative harmonic currents of a large number of non-linear single phase loads, particularlyPC’s and monitors, are investigated experimentally. In reference [1], it is shown, by means of ananalytical model, that there is a significant attenuation of

Gating current harmonics. II. Model simulations of axonal gating currents
Biophysical Journal, 1985 A kinetic model of sodium activation gating is presented. The kinetics are based on harmonic analysis of gating current data obtained during large-amplitude sinusoidal voltage clamp in dynamic steady state. The technique classifies gating kinetic schemes into groups based on patterns of the harmonic content in the periodic gating current records.
