At present, the power adapter
with high frequency has become the development direction. High frequency lessens the size of switch power supply, making the power adapter into a wider range of applications, especially in the high and new technology application field. This promotes the miniaturization of high technology products, and makes them much portable. In addition, the development and application of the power adapter have important significance in the aspect of saving energy, saving resources and protecting the environment.
