The rapid development of computer technology has led mankind into the information society, and has also promoted the rapid development of power module technology.
In 1980s, the computer * * adopted switching power supply, taking the lead in completing the replacement of computer power supply.
Then switching power supply technology has successively entered the field of electronic and electrical equipment.
With the development of computer technology, green computers and green power modules are proposed.
Green computer generally refers to personal computers and related products that are harmless to the environment. Green power supply refers to the high-efficiency power saving power supply related to green computers. According to the 'Energy Star' plan of U. S. Environmental Protection Agency l in June 17, 992, if the power consumption of desktop personal computers or related peripheral devices in sleep state is less than 30 watts, it will meet the requirements of green computers. Improving power efficiency is the fundamental way to reduce power consumption.
As far as the current 75%-watt switching power supply with an efficiency of 200 is concerned, the power supply itself consumes 50 watts of energy.
