i am going to design stabilizer to supply fix 220 VAC to 230VAC ..if source voltage is less then 220 VAC then my system should step it up and if voltage goes up from 230 VAC i.e .240 vac or more then my system should get off to protect my device for damage ....i have got the answer for over voltage and it works , i used comparator for it but still want some guide what should i do for step up if voltage comes less than 220 vac
