A Unified Active Damping for Grid and Converter Current Feedback in Active Front End Converters
IEEE Access, 2022 The Active Front End (AFE) is interconnected to the grid with an LCL filter to reduce the switching harmonics. Possible resonances induced by the LCL filter can be damped using Active Damping (AD). In AFE applications, the current sensor can be placed on

Robust Active Damping Control for LCL-Type Shunt Active Power Filters
IEEE Access, 2022 A dual-loop current control is discussed for LCL-type shunt active power filters (APFs), where inverter-side current feedback and point of common coupling (PCC) voltage feedforward both provide active damping (AD) effects for LCL resonance.

Active stabilization methods of electric power systems with constant power loads: a review
Journal of Modern Power Systems and Clean Energy, 2014 Modern electric power systems have increased the usage of switching power converters. These tightly regulated switching power converters behave as constant power loads (CPLs). They exhibit a negative incremental impedance in small signal analysis.

Energy Efficient Active Vibration Damping [PDF]
Linköping Electronic Conference Proceedings, 2013 Mining machines are subjected to severe vibrations during their operation. If we succeed to damp some of those vibrations then we have succeed to reduce the dynamic load of the machine and to improve operator comfort and productivity. The main idea for the research done in this paper is to investigate possible improvements in active vibration damping ...

Review of Magnetorheological Damping Systems on a Seismic Building
Applied Sciences, 2021 Building structures are vulnerable to the shocks caused by earthquakes. Buildings that have been destroyed by an earthquake are very detrimental in terms of material loss and mental trauma.
