A 1.25KVA (2000W) inverter generator was designed, constructed and certified Ok.

In this project, the design of the inverter generator  is aimed at satisfying the need of converting, a D.C source of supply (12v battery) to an A.C voltage of 220v.

The inverter range of output is between 200-220v.

Since the inverter was designed to step-up voltage, the power transformer is being used as step-down transformer for charging and as step-up transformer for inverting.

The control circuit ensures appropriate switching of the input voltage from mains supply to the taping of the transformer for charging.
