LARGE-OVERALL PERFORMANCE VFD PANELS FOR PRODUCTIVE INDUSTRIAL MOTOR VELOCITY REGULATION

For instance, with a standard 480 VAC 3-stage input voltage, the DC bus will hold a cost of about 650 VDC, with precise bus voltage dependant upon the line voltage degree and motor load. The explanation the DC bus voltage is higher compared to nominal enter line voltage is due to root-necessarily mean-squared measurements of AC sine waves (the “p
