Voltage Feedback based Harmonic Compensation for an Offshore Wind Power Plant [PDF]
, 2016 When an offshore wind power plant is connected to the grid, there is a risk of amplification of certain harmonics and appearance resonances at the point of connection due to the interaction between the grid network and the wind power plant network. Hence,

Effective Dead-Time Compensation Using Adaptive Harmonic Compensator
IFAC-PapersOnLine, 2015 Abstract This paper aims at analyzing and compensating the dead-time effects in the vector-controlled AC system. The use of dead-time in power electronics drive systems to prevent a short circuit in the DC link is necessary. However, dead-time can lead to distortion of VSI output voltage and ripple of phase current. It is used a feed-forward approach

HGCN: Harmonic Gated Compensation Network for Speech Enhancement
ICASSP 2022 - 2022 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), 2022 Mask processing in the time-frequency (T-F) domain through the neural network has been one of the mainstreams for single-channel speech enhancement. However, it is hard for most models to handle the situation when harmonics are partially masked by noise. To tackle this challenge, we propose a harmonic gated compensation network (HGCN). We design a high-

Imposing fair penalty to the harmonic sources based on the measurement data
IET Generation, Transmission & Distribution, 2021 Improving network power quality through harmonic reduction requires recognition of Harmonic Sources (HSs) to drive them to compensate their harmonics. This paper proposes a new method for equitable distribution of the Harmonic Compensation Cost of the ...

Third harmonic compensation in bridgeless current sensorless PFC [PDF]
2018 IEEE Applied Power Electronics Conference and Exposition (APEC), 2018 Single-phase Bridgeless power factor correction converters (PFCs) improve the conversion efficiency in comparison with the conventional PFCs, where a diode bridge plus a DC/DC boost converter are used, due to the absence of the input rectifier, but current sensing complexity increases.
