High-Effectiveness VFD Panels for Efficient Industrial Motor Pace Regulation
For instance, with a standard 480 VAC three-stage input voltage, the DC bus will keep a demand of about 650 VDC, with true bus voltage dependant upon the line voltage stage and motor load. The explanation the DC bus voltage is larger as opposed to nominal input line voltage is because of the root-mean-squared measurements of AC sine waves (the “p
