Description

A converter with a 6-pulse input rectifier absorbs from the mains a distorted current with a high harmonic content of lower rank. Absorption of non-sinusoidal current influences the voltage distortion which affects all of the devices supplied from the electrical grid. ElhandHFTM harmonic filters effectively limit the THDi value of the current.
