What element is changed to use the same appliance in US and in Europe ?

Hi,

We can often see the same household appliances in Europe, Asia or America even though the voltage is different.
They don’t use a heavy voltage converter, so what element is changed in the appliance in order to use it anywhere ?

Thanks

As the supply voltage differ at thes places the the voltage has to be stepped up or down depending on the supply voltage.

It is done by a step up or down transformer or by smps (switch mode power supply)

In some appliances it is built inside and the selection of voltages is done by a switch.
