Matrix drive benefits for managing drive harmonics

Oct 01, 2018

Matrix drives typically operate with less than 5% total harmonic distortion (THD) at the input of the drive. Courtesy: Yaskawa America Inc.Due to their control capabilities and efficiency improvements, variable frequency drives (VFDs) are widely used to operate electric motors. However, most conventional drives draw current non-linearly as part of their power conversion process and the resulting distorted current waveform means high harmonics are present. Large amounts of harmonics cause heating in upstream electrical equipment, reduce power factor, lower efficiency, and generate voltage harmonics, which can cause issues with IEEE 519.
