What is a single phase inverter?

Inverter is a power converter device, which converts fixed dc input voltage in to fixed or variable ac output voltage. Based on application and output power requirement various types of inverters are devised. Single phase inverters and three phase inverters are used to obtain single phase and three phase output ac voltage respectively.
