Constant AC voltage supply
Constant AC voltage supply
(OP)
I want to design a voltage optimisation device using a transformer approach. Is it possible (practically) to control the taps such that the output voltage stays at a CONSTANT value irrespective of the supply voltage?
Need wild Ideas.
Thanks

RE: Constant AC voltage supply
In the former case, a resonant constant voltage transformer does the job.
In the second case, there are Variacs with servo motors that keep the output voltage constant within one or two volts when input changes. Is that why you chose your nick?
Of course, it also depends on what power levels you are talking about. If more than a few kilowatts, none of the above is practical.

Skogs, you were typing same time I was. I agree with a resonant transformer for quick blips.

RE: Constant AC voltage supply
These days UPS systems seem to be default solution. In spite of the fact that they're a pain and seem to fail almost as often as the power.
RE: Constant AC voltage supply
The advantage of this approach is you're dealing with lower voltages. The disadvantage is less range (e.g. +/- 6.3 volts).

The idea is to keep the voltage at a fixed value of say, 230V despite changes in the supply. Ultimate goal is to save energy by keeping the voltage low instead of supply voltages that goes way high.

But I am thinking of using a transformer either with taps or some other mechanism
