For instance, with a typical 480 VAC 3-period enter voltage, the DC bus will keep a demand of about 650 VDC, with actual bus voltage dependant upon the line voltage amount and motor load. The main reason the DC bus voltage is increased when compared to the nominal input line voltage is a result of the root-indicate-squared measurements of AC sine waves (the “peaks” of a 480 VAC sine wave are here about 679 volts, which can be minus the ripple).
