The steady increase in non-linear loads on the power supply network such as, for instance, variable speed motor drives (VSDs), raises questions about power quality and reliability. In this respect, a ...
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 ...
For power supply harmonic mitigation, Schaffnerhas introduced the Ecosine active sync series – FN3530/31/40/41, FN3532/42 and FN3545. “By deploying Ecosine active sync filters it is possible to ...
Almost all off line switching power supplies over several kilowatts of output power use a three phase bridge rectifier. Typically, it comprises a six diode bridge and a DC bus filter capacitor. A ...
The PB-W (Wall-Mount) Series of three-wire and four-wire active (3x200VAC to 3x480VAC) harmonic filter modular systems are designed to meet IEEE-519. The Power Balance (PB-W) family is scalable and ...
The StacoSine® active harmonic filter line dynamically cancels problematic harmonics from the 3rd to the 51st order, allowing more efficient use of electricity, says the company. The active filter ...
A new IC-based approach to EMI filtering in ac-dc power subsystems dramatically cuts inductor size and offers other benefits as well. The nature of the EMI problem in ac-dc supplies and its ...
