Variable Frequency Drives
Looking for web reference on VFD efficiency when running on single phase input. I know effects of harmonics are worse when using single phase input, but power factor is improved with most VFD's. I need to know general efficiency loss estimates for cost analysis of bringing in three phase...- FreqOfNature
