Sentence examples for line frequency from inspiring English sources

Most of these motors are controlled by means of inverters that change the line frequency.

According to the achieved results and detailed analysis, maximum ripple of the calculated fundamental voltage amplitude is ±0.3% in normal condition of line frequency and ±1% in the case of ±1 Hz variation of 60 Hz line frequency.

In addition, the error between the actual fundamental voltage amplitude and the calculated one is almost zero in normal condition of line frequency and maximum of ±0.25% in the case of line frequency variation with excessive-harmonic distortion.

System power supplies often use band-rejection filters to suppress the 60-Hz line frequency and high frequency transients.

Also, the inverter output current is in sinusoidal waveform and in phase with line frequency and phase.

However, the equipment simply draws its power at harmonics of the line frequency as well as at the fundamental.

The equivalent circuit model of the in-line frequency discriminator is established and the measurement verification is also implemented.

A new construction of RF receiver front-end is then obtained by connecting the in-line frequency discriminator with the voltage controlling port of VCO.

To address the issue, the inherent relations among the DC error, double-line frequency error and inaccurate virtual current are discussed in the paper.

An improved virtual current method is proposed to eliminate the DC error and double-line frequency error, which are caused by frequency variations.

In addition, the base-line frequency of micronucleated erythrocytes (MN-RETs) by flow cytometry, HPRT mutants by a lymphocyte cloning assay, and chromosome aberrations by FISH painting were determined from peripheral blood samples.
