I want to supply electrical power, by starting with two double a batterys and reach 220 electrical supply. I don't want to loose
amperage in this process.

It's not a matter of amperage, it's a matter of power (volts * amps). The capacity of 2 AA batteries is about 3 volts * 1.5 Amps for 1 hour, which is 4.5 Watts for 1 hour. That's it! no more.
At 220 volts, 4.5 Watts will give you 20 milliAmps.
There are circuits for DC-220VAC inverters that will actually operate on 3 volts, but they are not very efficient (so you will get even less current at 220 volts -- probably 10 mA.
If you are still interested, edit your question with 'additional details' and I'll get you a link to some inverter circuits.

perhaps you could use a buck, and boost transformer.
