Harmonic Assessment Based Adjusted Current Total Harmonic Distortion [PDF]

open access: yesThe Journal of Engineering, 2016
Power systems suffer from harmonic distortion and extra ohmic losses associated with them. Moreover, all harmonic frequencies are mostly assumed to have the same effect on the system losses. However, the frequency-dependency of the resistances should be

A Study on the Harmonic Distortion of Seismic-Grade Sigma-Delta MEMS Accelerometers Using a Multiple Degree-of-Freedom Model [PDF]

open access: yesSensors, 2023
Harmonic distortion is one of the dominant factors limiting the overall signal-to-noise and distortion ratio of seismic-grade sigma-delta MEMS accelerometers. This study investigates harmonic distortion based on the multiple degree-of-freedom model (MDM)

Nonlinear Harmonic Distortion of Complementary Golay Codes. [PDF]

open access: yesUltrason Imaging, 2023
Recent advances in electronics miniaturization have led to the development of low-power, low-cost, point-of-care ultrasound scanners. Low-cost systems employing simple bi-level pulse generation devices need only utilize binary phase modulated coded excitations to significantly improve sensitivity; however the performance of complementary codes in the ...

A harmonic distortion standard [PDF]

open access: bronzeICASSP '83. IEEE International Conference on Acoustics, Speech, and Signal Processing, 1983
All harmonic distortion analyzer instruments may not give the same reading when measuring a particular audio range signal. A design method is presented that can supply a signal with a precisely determined amount of harmonic distortion. Digital signal generation technique is used. Factors which determine the accuracy of the signal are examined.

Harmonic Influencing Factors and Their Characterization Under Black Start Mode of Floating Power Station

open access: yes发电技术, 2022
When floating power stations use static frequency converters to black-start floating power station units, the harmonic effects are more serious than onshore power stations due to the isolated grid system and the limited electrical structure.

Study on harmonic source model of millisecond pulsed power load based on switching functions

open access: yesEnergy Reports, 2020
Modern radar is a typical millisecond pulse power load (MPPL), which contains a large number of power electronic devices. If the MPPL is connected to the power system, it will cause serious voltage distortion problems. The working mode of the radar pulse
