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.

∙ 13y agoTo 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.

What is the frequency of a alternating current source?
A/c 60 cycles
Compare alternating current with direct current?
Alternating current changes direction on a set frequency such as 50 Hz, 60 Hz or 400 Hz. Direct current always flows in one direction.
What measurement can vary with AC current by not DC current?
HZ. Hertz is the name given to the frequency of the alternating circuit. Direct current (DC) has no frequency since one wire is always positive and the other is always negative; but AC (Alternating Current) rapidly changes polarity, and does so at a rate that is defined by HZ.
What is the differences between direct circuit and alternating circuit?
The main difference between direct current (DC) and alternating current (AC) is the direction of the electrical flow. In a direct current circuit, the flow of electrons is in one direction, from the negative terminal to the positive terminal. In an alternating current circuit, the flow of electrons changes direction periodically, typically at a fixed frequency, resulting in an oscillating current flow. AC is widely used for electrical power distribution, while DC is commonly used in batteries, electronic devices, and certain applications like electric vehicles.
What does a transmission system at a radio station use to convert a direct current into a high frequency alternating current?
a high power, often class C amplifier.
What can observe when frequency increases in alternating current?
Dear Friend, we can observe over speed when frequency is increase in alternating current ANSWER: You will see that the time between peaks will shorten up. If rectified the amount of capacitance to reduce ripple will decrease.
what is a frequency converter?
A frequency converter is a power electronic device. It transforms Direct current to Alternating current of desired frequency and magnitude.
High frequency is direct or indirect current?
-- There's no such thing as 'indirect' current.-- Direct current has no frequency. As soon as you mention 'frequency',you're talking about alternating current.
Do strobe lights use ac or dc current to flash?
Strobe lights use ac or alternating current to flash. The frequency of 50 Hz is alternating current's frequency, coming in handy for its flashing.
What is the frequency of a alternating current source?
A/c 60 cycles
What is the purpose of a frequency converter?
A frequency converter converts "alternating current (AC) of one frequency to alternating current of another frequency." (Wikipedia) They are used to control the torque and speed of AC Motors. For more information go here: http://en.wikipedia.org/wiki/Frequency_changer.
What is frequency the current alternates in the US?
In the US AC current oscillates at 60 Hz.http://www.answers.com/alternating+current
Is transformer work without freqency?
No. A transformer has to have AC, alternating current, to work. And since it's alternating, it'll have a frequency.
What is the frequency of the alternating voltage and current typically used in the US?
60 Hertz
Does the capacitor's opposition to alternating current increase or decrease as the frequency of the current increases?
Capacitive reactance (expressed in ohms) is inversely-proportional to the supply frequency, so it will decrease when the frequency increases. The following equation applies:XC = 1/(2 pi f C)where:XC = capacitive reactance, in ohmsf = frequency, in hertzC = capacitance, in farads
Compare alternating current with direct current?
Alternating current changes direction on a set frequency such as 50 Hz, 60 Hz or 400 Hz. Direct current always flows in one direction.
What exactly does a frequency converter convert?
A frequency converter converts an alternating current from one frequency to another. This is typically measured in Hertz (Hz).
