How do you increase the frequency of Alternating Current?

Answer 1

There are two ways. If you want to increase the frequency by a huge amount and you want to do it on a permanent basis, install more magnets. An alternator that has one pair of field magnets and that turns at 3600rpm will generate 60-hertz electricity. If you put two pair of field magnets in it and turn it 3600rpm, it will generate 120-hertz electricity, and so on and so forth. (The other side of that is, if you want a certain frequency of electricity, the more pairs of magnets you install the slower the alternator has to turn. Install four pair of magnets in the generator, and you only need to run the engine at 900rpm--which makes it much quieter, a big advantage if the generator belongs to the army.) If you just need to adjust it a little, simply rev up the engine. If you have a generator that makes 60hz power at 3600rpm, accelerating the generator to 3660rpm will cause it to make 61hz electricity.

Answer 2

To increase the frequency of AC supply by increase the speed of the prime mover used for the alternator, the prime mover speed can be vary by stream input from the boiler is varied (or) using cycloconverter to change ie.. to increase the frequency of the AC supply.

Answer 3

you increase the amps and decrese the current
