TAILOR MADE VFD PANELS FOR MOTOR VELOCITY OPTIMIZATION IN VARIOUS UAE ASSIGNMENTS

For instance, with a typical 480 VAC 3-stage enter voltage, the DC bus will maintain a charge of about 650 VDC, with real bus voltage with regards to the line voltage stage and motor load. The explanation the DC bus voltage is larger compared to the nominal input line voltage is as a result of root-imply-squared measurements of AC sine waves (the â
