What does a high reliability supply look like?(1)


DC Module power

supply plays an important role in life. Basically, all products are inseparable from electricity. Therefore, power modules are widely used. Many household appliances have been used for a long time without breaking, indicating that the internal power module is reliable. What kind of high reliability supply is introduced in this paper? 

1: Use high-quality components. In fact, the difference between some cheap components and some expensive components is reliability. 

A modular power supply is a power supply that can be directly mounted on a printed circuit board and can be used for application-specific integrated circuits (ASICs), digital signal processors (DSPs), microprocessors, memories, field programmable gate arrays (FPGAs) and other Digital or analog loads provide power. Typically, such modules are referred to as load (POL) power supply systems or point-of-use power supply systems (PUPS). Due to the obvious advantages of the modular structure, modular power supplies are widely used in switching equipment, access equipment, mobile communications, microwave communications, optical transmission, routers and other communications fields, as well as automotive electronics, aerospace, etc.

2: When selecting device parameters, space should be reserved, such as withstand voltage. It is not allowed to assume that the market voltage is 220V. Generally speaking, we should consider that the voltage may be as high as 265V or even higher.
