Hi all.
i need a 48vdc to 220vac 50hz transformerless inverter design.

is it called as grid-tie inverter in electronics?

My time is limited and help please.
 

You will need a DC-DC boost from 48Vdc to 220Vdc then an inverter. This is for ideal case.
 

In place of Transformer you necessary use the inductor for the boost converter. then convert it to AC..

You use an inductor to boost the voltage to 250v or higher and then through PWM full-bridge converter, turn it to 220v 50hz.
