Three phase Inverter
Inverters are playing critical role in the Electrical system and widely used for the multiple application. Inverters are used to convert DC power to AC power. The DC power is generated by a sources like Battery, Solar Panel, Wind turbine etc. Inverters are used in Domestic, Commercial as well as Industrial applications. Mainly based on output power Inverters are classified in three main categories i.e. Pure Sine wave, square wave, Modified Sine wave.
