The chosen core is ETD39. The losses become evident as heat, generated in the (copper) wire windings as they dissipate power due to the resistance of the wire. Smaller cores require more turns for given power and frequency, to keep the core from saturating (saturated core will "disappear" and your coils will act like they are in free air). Transformer Turns Ratio Calculator Calculates the turns ratio needed to transform a given primary (non-reactive) impedance to a given secondary (non-reactive) impedance. Due to this, the transformer does not alter the voltage or current level. So you have to wind the step up transformer 12v to 220v but input winding must be capable to bear 20A. This equation is important! The transformer equation relates the number of turns of wire to the difference in voltage between the primary and secondary coils.
