A 110VAC voltage with a frequency of 60Hz is generated from a push-pull converter and a full-bridge inverter in a pseudo sine wave with a power of 600W. For this a 12VDC battery is used as power source. For the circuit to work properly a current limiter a voltage level sensor besides a protection system against high temperatures and input under-voltage was added to the control.Keywords: converter inverter push-pull full-bridge control.
