stabilizer circuit Needed 2

[law4eva]

hello it's been really long since i last posted .
well sorry for that.
here is my case .
i just moved into an area(in Nigeria) and found out that the voltage (due to overloading of the transformer) was 110v instead of 220v.
it just just made my life a living hell since i cant even do anything with such a very low voltage since most appliance here are rated 220v.
the voltage sometimes goes up to 220v thus blowing up any transformer that i must have switched to 110v.
what do i need? ...i need a stabilizer circuit(or something like it) to bring the voltage to 220v (stable) and to deliver a current of 15Amps.
and yes someone designed a 110v to 220v step-up but the problem is this anytime the voltage goes up to 220 from the mains i get close to 300v.
so what can i do?
thanks

Hi, there are things called constant voltage transformers, I don't think that they would cover that range though. The only other way is an electronic converter which would be very expensive. If you have lots of friends with the same problem then you could join together and get a local company to build something for you thus spreading the development cost.

Universal input switched-mode supplies that put out DC are off-the-shelf items, although a single 3kW unit is not going to be standard. Likewise a DC-to-mains inverter used for caravans, boats etc is probably straightforward. The simplest plug and go solution is to wire such units together, but break up the load so that you can use more reasonable power levels in each converter. The whole solution is not cheap, but then at 3kW you probably don’t expect it to be cheap.

thanks ..well i think the suggestion of meeting friends to get it done together would do the job.
thanks again
