What kind of 主词六替换 will be higher(1)

主词六替换 realizes voltage conversion. For example, when the mobile phone is out of power, it needs to be charged, but the 220v voltage cannot be directly used in the mobile phone, which will cause the mobile 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 will introduce you what kind of 主词六替换 to choose, which will be more secure?

Green module power
The rapid development of computer technology has led human beings into the information society, and also promoted the rapid development of module power technology. In the 1980s, computers fully adopted switching power supplies, taking the lead in completing the replacement of computer power supplies. Then switching power supply technology has entered the field of electronics and electrical equipment one after another. With the development of computer technology, green computer and green module power supply are proposed. Green computers generally refer to personal computers and related products that are harmless to the environment. Green power refers to high-efficiency power-saving power sources related to green computers. According to the "Energy Star" plan of the United States Environmental Protection Agency on June 17, 1992 If the power consumption of a small personal computer or related peripheral equipment in the sleep state is less than 30 watts, it meets the requirements of a green computer. Improving power efficiency is the fundamental way to reduce power consumption. For a 200-watt switching power supply with an efficiency of 75%, the power supply itself consumes 50 watts of energy.

主词六替换 One: circuit design principle and process

The quality of the resolution of the circuit schematic is usually done from a professional perspective. This power module can be divided into two kinds of bare board and packaged, according to an intuitive way of bare board, such as electronic components layout is reasonable and orderly, generous, orderly, and the net pad is lit upright. Also, stationary modules will not be able to see what's going on inside, but it's much better not to be exposed due to safety and performance levels. The soldering process can include both wave soldering and manual soldering, and the quality of the mechanized production process of wave soldering is superior to that of manual soldering.
