HIGHER-OVERALL PERFORMANCE VFD PANELS FOR OPTIMIZING INDUSTRIAL MOTOR MANAGEMENT

For instance, with a normal 480 VAC three-phase enter voltage, the DC bus will keep a demand of about 650 VDC, with true bus voltage with regards to the line voltage amount and motor load. The rationale the DC bus voltage is larger than the nominal enter line voltage is a result of the root-indicate-squared measurements of AC sine waves (the “pea
