For example, with a normal 480 VAC three-section enter voltage, the DC bus will hold a charge of about 650 VDC, with true bus voltage based on the line voltage level and motor load. The main reason the DC bus voltage is better compared to the nominal enter line voltage is because of the root-indicate-squared measurements of AC sine waves (the “pe
