Inverters are power generating devices that are able to convert DC battery potential to mains equivalent AC. These are personal power generators that can be used during mains power failure or during outings like picnics and camping. Basically an inverter consists of three stages viz: DC Source, oscillator circuit, and power transformer output stage. An inverter may be classified into a square wave design and a sine wave design.
Square wave inverters are very basic types involving a square wave oscillator stage which directly translates the DC low potential square wave oscillations into high voltage AC. These are never recommended for operating sophisticated electronic appliances like TVs, music systems, computers etc.
Sine wave inverters are more complicated in design but the output from these inverters become ideally suitable
