For example, with an average 480 VAC 3-period enter voltage, the DC bus will keep a demand of about 650 VDC, with actual bus voltage depending upon the line voltage stage and motor load. The reason the DC bus voltage is larger in comparison to the nominal input line voltage is a result of the root-necessarily mean-squared measurements of AC sine wa
