Sinusoidal alternating current means that the current, voltage and electric potential in the circuit change according to the sine function law with time. This kind of current whose size and direction changes periodically with time is called alternating current, or alternating current for short.
Alternating current can be used to transform voltage through a transformer. During long-distance transmission, the voltage can be increased to reduce line loss. When in use, the high voltage can be changed to low voltage through a step-down transformer, which is beneficial to safety and can reduce the insulation requirements of the equipment. In addition, compared with DC motors, AC motors have the advantages of simple structure, low cost, and easy maintenance. In some places, DC power is needed, and AC power can be converted into DC power through rectifier equipment, so AC power is currently widely used.
Application of sinusoidal alternating currentSinusoidal alternating current is widely used in industry. Compared with direct current, it has many advantages in production, transmission and application. Moreover, sinusoidal alternating current changes smoothly and is not easy to generate high-order harmonics, which is beneficial to protect the insulation performance of electrical equipment and Reduce energy loss in the operation of electrical equipment. In addition, various non-sinusoidal alternating currents can be formed by superimposing sinusoidal alternating currents of different frequencies (using Fourier analysis), so the analysis method of sinusoidal alternating current can be used to analyze non-sinusoidal alternating current.
Sinusoidal alternating current has a wide range of applications in life, the most basic is lighting, all kinds of small electrical appliances, and car batteries are also converted by it.
However, in a wide range of applications, we cannot directly apply AC power, which requires voltage stabilization and filtering, such as the power supply of various small household appliances. If AC power is directly introduced, the pulsating current will instantly burn the appliance, which requires We know the voltage and current values ​​required by electrical appliances. They are suitable for electrical work through transformation. It is worth mentioning that years of work experience tells me that voltage stabilization and filtering play a very important role in the overall performance of electrical appliances. Electrical appliances are not stable due to poor filtering, which burns down the electrical appliances.
However, car battery charging has relatively loose requirements for voltage stabilization and filtering. This is because an ordinary battery itself is regarded as a capacitor. If you charge it with a smooth trickle after filtering, it will be It takes time and effort to achieve results. The battery needs a very pulsating current. Of course, this environment is not very strict.
In fact, we have been living in alternating current, such as mobile phone pager signals, various electronic wireless transmission radiation, human body functions, and resonance principles.
Almost all life forms in the universe, unknown life, including objects that have no life characteristics in the eyes of humans, almost all have alternating current, which is just a subtle point. Humans should conduct more in-depth research in this profession.
Significance of the development of sinusoidal alternating currentSinusoidal alternating current has very important significance in practice and theory.
Non-sinusoidal alternating current may cause additional power loss in electrical appliances (such as motors), may cause harmful high voltages in certain parts of the circuit, and may cause interference to telecommunication lines.
Therefore, sinusoidal alternating current is commonly used in power plants to provide industrial and civil alternating current. The law of sine function is relatively simple, and any periodic function can be written as the sum of many sine functions of different frequencies.
Applying the law of sinusoidal alternating current can decompose any alternating current into sinusoidal alternating current for discussion, which is extremely useful in electrical engineering and electronics. Sinusoidal AC power can be transformed by a transformer and boosted during long-distance transmission to reduce line losses and obtain the best economic benefits. The user can turn the high voltage into low voltage through the step-down transformer, which is safe and can reduce the insulation requirements of the equipment. AC motors are simple in structure, low in cost, easy to maintain, and widely used.
