Power adapter is a revolution in the history of power adapter in the 1960s. We should not be unfamiliar with power adapter. Mobile phones, laptops and power adapter are indispensable. In addition to the applications in laptops, which fields are they suitable for? Jiuqi power adapter manufacturers to share: it is installed in various household appliances, industrial equipment and military electronic devices, and is used in various fields as an enabling device. Here are some examples of power adapter applications.
1. Metal welding and cutting power adapter
About 50% of the steel produced in the world can be used only after welding and processing into components. For every 10000 tons of steel, 200000 ~ 250000 welding machines need to be produced to meet the processing demand. The high-frequency switching rectifier welding wifi adapter desktop pc power adapter is unmatched by the traditional welding power adapter in terms of volume, quality, energy saving and welding performance. It has replaced the traditional welding power adapter and is widely used in the welding industry.
2. Surface treatment works
Rectifier power adapter for electroplating industry, which is characterized by low voltage and high current. Compared with diode silicon rectifier power adapter and thyristor rectifier electroplating power adapter, high-frequency inverter switch rectifier electroplating power adapter not only has small volume, light weight and high efficiency, but also has the advantages of good controllability, high precision of voltage and current stabilization, easy parallel connection, easy to realize computer monitoring and fault detection safety control, and the coating quality is greatly improved. The combination of DC electroplating and pulse electroplating can obtain a uniform, crack free, corrosion-resistant and wear-resistant coating surface.
Arc thermal spraying process for industrial equipment, weapon equipment and ship maintenance, using high-frequency power adapter arc as heat source, has a wide application prospect for realizing dense coating structure, low porosity, high strength, wear resistance and thermal corrosion prevention.
For plastic surface treatment, the high-voltage power adapter with working voltage of 10 ~ 13kv and switching frequency of 10 ~ 36kHz is used to modify the plastic surface by corona method to improve the printability and adhesion. This method can also remove oil, water vapor and dust at the same time.
Used for surface treatment of capacitor aluminum foil, which can improve the specific capacity and electrical strength of capacitor.
3. Application in environmental protection
Pulse corona plus ammonia desulfurization is a promising flue gas purification technology, which has its application in solving acid rain, one of the three major environmental protection problems in the world.
High frequency power adapter has also been widely used in pulse discharge wastewater treatment. The plasma generated by strong pulse discharge can store energy with high density and has high expansion effect. It can form strong heat energy, expansion pressure heat energy, light energy, sound energy and radiation energy, and then produce various free radicals in water. These active free radicals can destroy harmful substances in industrial wastewater.
The use of power adapter in pulsed electric field sterilization and disinfection can overcome the limitations of sterilization such as heat treatment and preservatives, and avoid introducing new pollution to food. Strong pulse discharge, especially the strong shock wave generated by high-voltage pulse discharge, as well as the comprehensive effects of ultraviolet, strong current and ozone, has higher sterilization effect and energy utilization rate.
4. Application in laser
Laser is used in the fields of national defense, industrial processing, medical and health care, such as range test, lethal weapons, detection, defense, drilling, forming, mold repair, surgery, repair, etc. The power adapter of laser is powered by high-frequency power adapter, which overcomes the shortcomings of thyristor switch and opens up a broad prospect for the development and application of laser technology.
5. Application in power system
Using AC-DC and DC-DC high-frequency power adapters in the power operation system can realize the hot standby operation with the commercial power. It can not only charge the battery with the commercial power under normal conditions, but also provide the operating power adapter required by the load when the commercial power is cut off, which overcomes the shortcomings of large volume and poor accuracy of silicon rectifier and diode voltage regulation. High voltage and high power switching converters are needed in power transmission and distribution systems.
6. Application in communication field
Power adapter has been used in communication system for a long time, and its technology is becoming more and more mature, mainly including primary power adapter (such as 48V DC power adapter) and secondary power adapter (such as 24V, 12V, 6V DC power adapter)
7. Application in battery charging
In the past, silicon diodes and thyristor rectifier power adapters were used in large capacity battery charging devices. Using the power adapter to charge the battery is not only small in size and light in weight, but also can realize the control of computer or single chip microcomputer. The charging parameters are more in line with the acceptance rate of the battery, and the charging efficiency is high. It can realize fast charging and improve the service life of the battery. As a tool for battery energy regeneration, the power adapter charger has a good application market, especially for charging electric vehicle batteries.
8. Application in wind and solar power generation
Wind energy and solar energy are renewable energy, which are of great significance to save energy and reduce environmental pollution. DC-DC and DC-AC switching converters are widely used in wind and solar power generation systems because of their small size, light weight, high efficiency and low noise.
9. Application in motor speed regulation
About 60% of the world's electricity consumption is consumed by motors. How to make the motor work in high efficiency is of great significance. Power adapter frequency converter can play an important role in this field.
10. Application in military equipment
The installation of power adapter in military electronic equipment has become one of the characteristics of modern military electronic equipment. The power adapter is used for the start-up control, training and ignition of tanks, artillery and missile launcher, which improves the effect and combat effectiveness of military training and saves military expenditure.
In all devices and equipment using power adapter, power adapter has a place to play. From civil electrical appliances to industrial equipment and military equipment, power adapter applications are everywhere.
There are also some security monitoring, medical equipment and so on. Power adapter is an indispensable part of our life. It is very difficult to include its application. The application fields listed above are only a few examples for reference. Application is the purpose of design and manufacturing, and it is also the key to promote designers to design products correctly.
