HIGHER-GENERAL PERFORMANCE VFD PANELS FOR SUCCESSFUL INDUSTRIAL MOTOR PACE REGULATION

As an example, with a typical 480 VAC three-section enter voltage, the DC bus will keep a cost of about 650 VDC, with true bus voltage depending upon the line voltage amount and motor load. The main reason the DC bus voltage is higher in comparison to the nominal enter line voltage is because of the root-indicate-squared measurements of AC sine wav
