4. Alternating Current (AC) Generators: How They Work and Examples

Alternating current (AC) generators are electromagnetic devices that convert mechanical energy into electrical energy. These generators work through a process called electromagnetic induction, which is based on the principle that a time-varying magnetic field can generate an electric current in a conductor. The alternating current generated by these devices is characterized by changing direction periodically, which distinguishes it from direct current (DC) that flows in only one direction.

The operation of an alternating current generator can be divided into several stages. First, a rotor, which can be made up of magnets or electromagnets, rotates inside a stator. The stator has wire windings that form the coils of the generator. As the rotor rotates, it creates a time-varying magnetic field that induces an electric current in the stator coils. This generated current is an alternating current, since its direction is constantly changing due to the movement of the rotor.

There are different types of alternating current generators, each with its own design and specific applications. Some common examples include alternator generators, synchronous generators, asynchronous generators, and induction generators. These generators are used in a wide variety of industries, such as electrical power generation, the automotive industry, and the construction industry. Additionally, they are also used in smaller applications, such as in automotive battery charging systems or in portable generators for home or outdoor use.

Synchronous generators are electrical machines that convert mechanical energy into alternating current electrical energy. Their operation is based on the principle of electromagnetic induction and synchronization of the rotor speed with the frequency of the electrical network to which they are connected.

The operation of a synchronous generator is governed by the basic principles of Faraday's law and Lenz's law. When a conductor moves in a magnetic field, a voltage is induced in the conductor. In the case of synchronous generators, this magnetic field is generated by the rotor, which is made up of an electromagnet or permanent magnet. As the rotor rotates, induced currents are generated in the windings of the armature, which results in the generation of electrical energy.

Synchronous generators have numerous applications in industry, power generation and transportation. They are commonly used in power plants to generate electricity on a large scale as they are capable of providing a constant voltage and frequency.

One of the most important features of asynchronous generators is their ability to produce multiple values ​​throughout their execution. This is possible thanks to the "yield" keyword, which allows the generator to produce a value and suspend its execution until it is resumed. These types of generators are especially useful when working with asynchronous operations, such as requests to servers or access to databases.

In addition to their ability to produce multiple values, asynchronous generators can also receive values ​​from outside using the next() function. This allows bidirectional communication between the generator and the code that calls it, which is useful for passing information or controlling the flow of execution. Thanks to this feature, asynchronous generators are widely used in handling asynchronous tasks in web applications and in the development of JavaScript frameworks and libraries.
