What kind of input will be more safe?(1)


Module power

The power module realizes voltage conversion. For example, when the phone is out of power, it needs to be charged, but the 220V voltage cannot be directly used on the phone, which will cause the phone to burn. At this time, a conversion device is needed to convert the voltage that the mobile phone can use. This conversion device is the power module. This article introduces what kind of input will be selected for higher security?

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.

1: The quality and resolution of circuit design principles and process circuit schematics are usually from a professional perspective. The power module can be divided into bare board and package board. In an intuitive way, the bare boards such as electronic components are arranged in a reasonable and orderly manner, and the cleaning pads are lit vertically. In addition, fixed modules will not be able to view the internal situation, but this is much better because the security and performance levels are not disclosed. The welding process can include wave welding and manual welding. In the mechanized production process of wave welding, the quality of wave welding is better than that of manual welding.
