Emis of Sweden has a range of three-phase passive harmonic filters intended to minimise harmonic distortion with non-linear loads such as variable frequency drives (VFDs), uninterruptable power ...

The major drawbacks of conventional diode or thyristor rectifiers are overcome by active power factor correction; this further provides additional benefits. Operating principles and features of single ...

Power factor correction for mains rectifiers is an upcoming issue. Operating principles of single and three phase power factor corrected rectifiers have been explained. Suitable integrated power ...

Last month, we discussed low power factor and how resonance can disrupt facility operations. This month, we'll talk about harmonic filter design and various system parameters that affect filter ...
