As an example, with an average 480 VAC 3-stage input voltage, the DC bus will maintain a cost of about 650 VDC, with real bus voltage depending on the line voltage amount and motor load. The key reason why the DC bus voltage is increased than the nominal enter line voltage is due to root-necessarily mean-squared measurements of AC sine waves (the �
