For example if the motor was connected in delta it would accept a three-phase input voltage range of 220-240V for a 50Hz supply frequency or 250-280V for 60Hz frequency. Similarly with the motor connected in star an input voltage range of 380-420V is acceptable on 50Hz or 440-480V on a 60Hz supply system.
Analog to Digital Conversion

It charges a capacitor over a fixed period with a current proportional to the input voltage. Then, the time required to discharge the same capacitor under a constant current determines the value of the input voltage.

DC to AC Converters Inverters - Engineering
www.site.uottawa.caOutput of the inverter is “chopped AC voltage with zero DC component”. It contain harmonics. An LC section low-pass filter is normally fitted at the inverter output to reduce the high frequency harmonics. In some applications such as UPS, “high purity” sine wave output is required. Good filtering is a must.
