hello,
why we use a sinusoidal voltage source and no others (square, saw waves ...)?

I_am_learning said:Also, because that's the best wave to have it transformed between different voltage levels using transformers.
For detailed explanation you need to study about the working of Transformers. But to put it shortly, as technician pointed out, if you put in sinusoidal wave into transformer, you get sinusoidal wave out. It won't happen for other cases. So, if you need to keep on transforming voltage levels using transformers, and if you need to preserve your wave shape (if you don't want to, then why would you desire for particular wave shape anyway? ), then your best option is to use sinusoidal waves.Essadaoui_Red said:
i need more explanation !
Essadaoui_Red said:thank you all,
after your explanations, i tried to summarize the advantages of sine as follows:
- At power generation, the sine shape is naturally generated by alternative motor (synchronous),that more advantageous than DC Motor,
- in transmission: sine is the most appropriate to vary by a transformer and with less waste and harmony,
- Distribution: the sine signal are avoided during an abrupt voltage variation (this is not the case for other forms: square ...).
is that it's just my abstract ??
Integral said:As a side note. Most power inverters, that is the device that converts 12VDC to 120VAC, in your car do NOT produce a sine wave. That is why some devices have troubles with them.
Alternative current sinus is a type of electrical current that flows in a sinusoidal pattern, meaning it moves back and forth in a smooth, continuous motion. It is the most commonly used type of electricity in homes and buildings.
The main difference between AC and DC is the direction in which the electricity flows. While AC moves in a back and forth motion, DC only flows in one direction. AC is also able to be transmitted over long distances, while DC is better suited for short distances.
One of the main advantages of AC is its ability to be easily transformed into different voltage levels, making it more versatile for different applications. Additionally, AC is able to be transmitted over long distances without significant loss of energy.
AC is generated through power plants, where mechanical energy is used to rotate a turbine, which then turns a generator. The generator converts this mechanical energy into electrical energy in the form of AC.
AC is used for a variety of purposes, including powering homes and buildings, running appliances and electronics, and even charging electric vehicles. It is also used in industrial applications such as manufacturing and transportation systems.
