An autotransformer would be the most efficient, but you would have to change the taps as the voltage varies.
You haven't said how much power you need.

Which country are you in?
Are you willing to accept a range of voltages as acceptable, say 220 - 250?
What KVA?
If in India,

Need is ~ 330 - 540 Watt
this need is for every ~ 3 days in 25-30 minutes duration as it just for front-load washing machine

That's exactly illustration of indecent power grid infrastructure in my area
