Module power supply: efficient and reliable power supply solution
Author： ZYG Power Module Time： 2024-11-25
Module power supply, also known as power module, board mounted power supply, is a power supply that can be directly mounted on a printed circuit board. The following is a detailed introduction to module power supply:
1. Main features
Simple design: Module power supply is usually equipped with standardized front end, highly integrated power module and other components. When in use, only one power module is needed, with a small number of discrete components, to obtain power supply, which simplifies the power supply design.
Shorten the development cycle: Module power supply generally has a variety of input and output options. Users can repeat or cross-stack as needed to form a building block combination power supply, realize multi-channel input and output, thereby reducing the prototype development time.
Flexible changes: If the product design needs to be changed, just convert or parallel another suitable power module.
Standardized packaging: The module power supply shell has a trinity structure of heat sink, radiator and shell, which realizes the conduction cooling method of the module power supply, makes the temperature value of the power supply close to the minimum value, and gives the module power supply standardized packaging.
High quality and reliability: Module power supply is generally fully automated and equipped with high-tech production technology, with stable and reliable quality.
Combinability: The module power supply can be combined according to actual needs to achieve flexibility and scalability, which is convenient for users to combine and upgrade according to their needs.
Efficiency: The module power supply adopts advanced power conversion technology, which can achieve efficient energy conversion and utilization, and reduce energy loss and waste.
2. Main advantages
High reliability: Each module of the module power supply is independent, and can be replaced separately when a fault occurs, without affecting the operation of the entire system. At the same time, the module power supply can use redundant design to improve the reliability and stability of the system.
High power density: The module power supply emphasizes the standardization of packaging, and the product has the characteristics of small, thin and light, which can greatly improve the power density.
Good maintainability: The module power supply is maintainable, and a single module can be quickly replaced when it fails, shortening the maintenance time and improving the availability and stability of the equipment.
3. Product classification
According to the application field of modern power electronics, the module power supply can be divided as follows:
Green module power supply: refers to the high-efficiency and energy-saving power supply related to green computers. Green computers generally refer to personal computers and related products that are harmless to the environment, while green power supplies improve power efficiency to reduce power consumption.
High-frequency switching power supply: High-frequency miniaturized switching power supplies and their technologies have become the mainstream of modern communication power supply systems. In the field of communications, rectifiers are usually called primary power supplies, while DC/DC converters are called secondary power supplies.
DC/DC converters: convert a fixed DC voltage into a variable DC voltage. This technology is widely used in stepless speed change and control of trolleybuses, subway trains, and electric vehicles.
Uninterruptible power supply (UPS): a highly reliable and high-performance power supply required for computers, communication systems, and occasions that require uninterrupted power.
Inverter power supply: mainly used for variable frequency speed regulation of AC motors, it occupies an increasingly important position in electrical transmission systems and has achieved huge energy-saving effects.
In addition, module power supplies can also be subdivided into general module power supplies, railway module power supplies, aerospace and military module power supplies, and thick film process power supplies, which are used in different downstream industries.
In summary, as an important component of electronic equipment, module power supplies have broad application prospects and huge market potential. With the continuous advancement of technology and the continuous expansion of application fields, module power supplies will become more intelligent, efficient, and reliable, providing more reliable guarantees for the stable operation of electronic equipment and systems.

AC DC power supplies are essential components in many electronic devices and systems. They provide a stable and reliable source of power to ensure the proper and safe operation of the equipment. Among the various types of AC DC power supplies available, the power factor correction (PFC) series is one of the most efficient and widely used. The PFC series is designed to correct the power factor of the AC input to a high value, typically above 0.9. This means that the power supply draws less current from the AC mains for the same output power, resulting in lower power consumption and reduced energy costs. In addition, the PFC series reduces the harmonics and noise generated by the power supply,...
