MEAN WELL switching power supply is known as high-efficiency and energy-saving power supply, which represents the development direction of stabilized power supply and has become the mainstream product of stabilized power supply.

Introduction to MEAN WELL switching power supply

　　In terms of structure, MEAN WELL switching power supplies are generally composed of pulse width adjustment (PWM) control integrated circuits and MOSFETs. With the development and innovation of power electronics technology, switching power supplies are mainly used in most electronic devices with the characteristics of small, lightweight and high efficiency, and its importance is obvious.

Generally speaking, MEAN WELL switching power supply can be divided into three categories: series switching power supply, parallel switching power supply, and transformer switching power supply. Among them, the transformer switching power supply can be further divided into: push-pull type, half-bridge type, full-bridge type, etc.; According to the excitation of the transformer and the phase of the output voltage, it can be divided into forward excitation, reverse excitation, single excitation and double excitation.

With the progress of science and technology, especially the update of power devices, the continuous improvement of power conversion technology, the continuous use of new electromagnetic materials, the continuous improvement of control methods, and the continuous development of related disciplines, switching power supply has become the product of multidisciplinary technology integration. Moreover, MEAN WELL switching power supply is also keeping up with the trend of the times, constantly optimizing and innovating to ensure that it does not lag behind.

At present, the function of domestic communication high-frequency switching power supply is close to that of foreign products, but there are still differences in performance, which is mainly manifested in insufficient reliability and stability. The lack of systematic, modular, and engineering design methods and necessary simulation methods is the reason why the system cannot work properly. However, MEAN WELL switching power supply is an exception, and its technical content and quality are different from foreign products.

All in all, the development direction of MEAN WELL switching power supply is: the frequency should be high, so that the dynamic response is fast, which is also necessary for high-speed microprocessors; The volume should be small, and the transformer, inductor, and capacitor should be small; The efficiency should be high, the heat energy generated should be small, the heat dissipation should be small, and it is easy to achieve high power density, so as to produce high-frequency switching power supply with ultra-high power; High level of integration of the power supply system.
