With the development of consumer electronics, energy consumption rate in global electricity of its external power supply(adopter) is dramatically increasing which has been seen as a great energy consumption user.Take America as example, adapters consumes 300 billion degrees electricity per year and it is 11% of the entire country electricity.Today energy conservation and emission reduction is pervasive,at present all governments' regulations are more and more strict to exteral power supply.The United States energy star makes more strict regulations to the average efficiency for external power supply. Figure 1 shows the power efficency when the output voltage is lagrger than 6V.
