PdL Posted December 2, 2011 Report Posted December 2, 2011 Has anyone used this new Yaskawa Varispeed AC inverter? http://www.yaskawa.eu.com/en/products/inverter-series/varispeed-ac/introduction.html As opposed to conventional drives it does not have an intermediate DC switching circuit which greatly reduces the harmonic currents distortion expecially when using generator power. Without any additional DC reactor or chokes it claims to reduce harmonics to <6%. Together with reduced energy footprint, this might just be the electric AC drive of the future. Matrix.pdf Quote
