High frequency switching power supply 高频开关电源

–M–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. –W–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. –T–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.
