As an example, with a standard 480 VAC 3-stage input voltage, the DC bus will keep a demand of about 650 VDC, with actual bus voltage according to the line voltage amount and motor load. The explanation the DC bus voltage is increased when compared to the nominal input line voltage is due to the root-necessarily mean-squared measurements of AC sine
