Reactors for AC drives are available as either AC reactors or DC reactors (DC link chokes). Both serve the same main purpose: to smooth the current flow to the AC drive, and reduce damaging harmonics ...

At one time, almost all electrical loads were linear — those that weren't made up such a small portion of the total that they had little effect on electrical system operation. That all changed, ...

Two CDs have been released to help the user with understanding variable-frequency drive (VFD) technology and to provide a simple method of calculating harmonic voltage and current distortion when ...

SOLV harmonics analysis software is a powerful simulation program that calculates current and voltage distortion levels in variable-frequency-drive (VFD) systems and provide Mirus Lineator harmonic ...

With the rising demand of non-linear type equipment and loads, mitigation of harmonics becomes increasingly important. If a harmonics study or testing indicates excessive harmonic levels or a ...

Harmonic distortion arises when electrical waveforms deviate from their ideal sinusoidal shape, typically through the proliferation of nonlinear loads such as power electronic converters, ...

Increasingly common, variable frequency drives (VFDs) are used to control motor speed — elevating the frequency of power pulses/sec fed to motors for faster turning, and decreasing that frequency to ...
