Nettet1. Classification of Inverters. An inverter plays a very prominent role in grid-synchronization and is responsible for DC–AC inversion [].Inverters are generally categorized into line commutation inverters (LCI) and self commutation inverters (SCI) based on the commutation process (turned ON and turned OFF behavior). Inverter is the device which converts DC into AC is known as Inverter. Most of the commercial, industrial, and residential loads require Alternating Current (AC) sources. One of the main problems with AC sources is that they cannot be stored in batterieswhere storage is important for backup power. This flaw can … Se mer The inverter can be defined as the device which converts DC input supply into AC output where input may be a voltage source or current source.
