For example, with a normal 480 VAC 3-stage enter voltage, the DC bus will hold a demand of about 650 VDC, with real bus voltage based on the line voltage amount and motor load. The explanation the DC bus voltage is better in comparison to the nominal enter line voltage is because of the root-signify-squared measurements of AC sine waves (the “pea
