Advantages and functions of high-voltage input module power supply(1)

With the development of the electronic industry, the high-voltage input module power supply is required to be smaller and more reliable. With the development of high-frequency soft switching technology, semiconductor technology and packaging technology, the power density of the power module is getting higher and higher, the conversion efficiency is getting higher and higher, and the application is simpler.

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.

What are the advantages of the power module compared with the separate scheme? In addition to saving cost and development time, the power module scheme has many advantages.

Advantages of high-voltage input module power supply:

1. Simple design

At present, there are many kinds of modules in the market, such as AC-DC, DC-DC, high-voltage modules, etc. You only need to select a suitable power supply module with a small number of discrete components to use. The high integrated circuit inside the module makes the design more compact. The supplier can also provide professional technical support and system solutions. The biggest difference from the split type is that manufacturers can provide important data such as models, peripheral circuits, and parameter curves of modules.
