STATE-OF-THE-ART VFD PANELS FOR OPTIMIZING INDUSTRIAL MOTOR CONTROL IN UAE

As an example, with an average 480 VAC three-period input voltage, the DC bus will hold a charge of about 650 VDC, with genuine bus voltage depending on the line voltage amount and motor load. The reason the DC bus voltage is larger in comparison to the nominal input line voltage is due to root-indicate-squared measurements of AC sine waves (the �
