– My research areas is the switching power supply（开关电源） ,it is a branch of power electronic technology.there are many types of switching power supply .

– What is the switching power supply ? It is use semiconductor devices as a switch , it can transform one electrical power source from one form to another. It is defined as Switching Converter. It is output stability in a automatic control system. A device that has this function usually be defined as Switching Power Supply.

– There are many types of switching power supply ,and it is very useful in the area of national economy. I will Take a High frequency switching power supply （高频开关电源） for instance.
