Advantages and functions of non-isolated power supply(1)

With the development of the electronic industry, the non-isolated 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.

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 non-isolated power supply:

1. Simple design

●Low technical requirements. Modular power supplies are typically equipped with standardized front ends, highly integrated power modules and other components, thus simplifying power supply design.
●The module power supply shell has a three-in-one structure of heat sink, radiator and shell, which realizes the conduction cooling mode of the module power supply and makes the temperature value of the power supply approach the minimum value. At the same time, the normative packaging of the module power supply is given.

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.
