A cooperative control strategy for power quality based on parallel grid-connected converters

open access: yes电力工程技术
Power quality control based on grid-connected converter can effectively utilize the surplus capacity of the converter and improves the benefits. However, existing methods tend to only consider grid-following (GFL) control and fail to fully utilize the ...

Harmonic Current Suppression of Dual Three-Phase Permanent Magnet Synchronous Motor with Improved Proportional-Integral Resonant Controller

open access: yesEnergies
The impedance of the harmonic plane in a dual three-phase permanent magnet synchronous motor (DTP-PMSM) is very low, meaning that even small harmonic voltages can induce significant harmonic currents, particularly at the fifth and seventh harmonic ...

Rethinking Charge Transport and Recombination in Donor‐Diluted Organic Solar Cells

open access: yesAdvanced Materials, EarlyView.
Organic solar cells with 1–45% PM6 content in Y12 were studied to link structure and charge dynamics to performance. The conductivity follows a 3D percolation model without a sharp threshold. Donor dilution preserves the photogeneration yield, but limits the fill factor due to transport resistance losses.

Compensation of harmonic disturbances in piezoelastic structures [PDF]

open access: yesMathematical and Computer Modelling of Dynamical Systems, 2011
The use of self-sensing piezoelectric actuators in smart structures means collocation of actuator and sensor. The measured electric current carries contributions from an electrical and mechanical subsystem. The latter contribution is due to the direct piezoelectric effect that is used for the purpose of vibration control.
