According to the output voltage and current phases, inverters are divided into two main categories. Single-phase inverters and three-phase inverters. These categories are briefly discussed here. .
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. .
Silicon controlled rectifiers are mainly divided into two main types according to commutation techniques. Line commutated and. .
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. Inverters are mainly classified into two main categories. Inverters used in applications with high currents and voltage are known as power inverters. Inverters used in applications with low currents and voltages are known as oscillators. Circuits that do the opposite–convert AC to DC–are called rectifiers. [pdf]
