Temperature range and derating useGenerally, power modules of manufacturers have several temperature range products to choose from: commercial grade, industrial grade, military grade, etc. when selecting module power supply, we must consider the actual working temperature range, because different te

Selection of DC-DC module power supplyIn addition to the most basic voltage conversion function, the following aspects need to be considered when choosing to use DC / DC module power supply:1. Rated powerIt is generally recommended that the actual power used should be 30-80% of the rated power of th

The following are the three elements of a low ripple power supply:1. Energy storage inductance. The larger the Q value of the energy storage inductance at the working frequency, the better. Many people only pay attention to the inductance. In fact, the influence of Q value is much larger. As long as

In the modern high-tech era, the higher the reliability of DC-DC power modules, but AC-DC power conversion and DC-DC power conversion have gradually become module or integrated chip industry, and also gradually become an important part of various electronic equipment and industrial automatic control

1. SecurityIsolated DCDC power module refers to the isolated power supply that uses transformers to reduce the voltage of various voltages (such as 48VDC, 24VDC, 12VDC, etc.) to the required voltage through transformers, and then supplies power to the load. The non isolated power supply module direc

1、 Cost analysis of power supply schemeIn the development of electronic systems, many design engineers will choose to build their own power supply solutions, mainly for the purpose of saving costs and confidence in their own power supply technology. People think that the cost of the power supply sy

In recent years, the application of modular power supply has become more and more extensive, and the requirements for it in the design of electronic products have become higher and higher. Especially in recent years, the rapid development of the electronic industry, the improvement of the traditiona

There are many kinds of switching regulated power supply, but the basic circuit is composed of linear filter, rectifier filter, DC / DC converter and regulated control circuit.The AC voltage of 220V / 50h: passes through the linear filter, filters out the pulse interference in the power grid, and th

With the rapid development of power electronics technology, the relationship between power electronics equipment and people's work and life has become increasingly close, and electronic equipment can not be separated from reliable power supply. In the 1980s, computer power supply fully realized

Because the module power supply is easy to install and has many structural advantages, the design related to the module power supply often appears in the field of mobile communication and switching equipment. It can be seen that the module power supply is widely used. The DC-DC power module has high
