Switching Power Supply is a kind of power supply that uses modern power electronic technology to control the time ratio of switching tube on and off to maintain stable output voltage. Switching power supply is generally modulated by pulse width (PWM)Control IC and MOSFET composition. With the prospect of power electronics technology and * *, the switching power supply technology is also constantly **. At present, switching power supply is widely used in almost all electronic facilities with the characteristics of small size, light weight and high efficiency, which is an indispensable power supply mode for the rapid prospect of electronic information industry today. With the high-speed prospect of power electronic technology, the relationship between power electronic facilities and people's work and life is increasingly close, and electronic facilities cannot be separated from reliable power supply, in 1980s, the computer power supply * * realized the switching power supply, took the lead in completing the Power replacement of computers, and in 1990s, the switching power supply successively entered various fields of electronic and electrical facilities, the switching power supply has been widely used in program-controlled switches, communication, electronic detection facilities power supply, control facilities power supply, etc. , which has promoted the rapid prospect of switching power supply technology. Compared with linear power supply, the cost of switching power supply increases with the increase of output power, but the growth rates of the two are different. The cost of linear power supply is higher than that of switching power supply at a certain output power point. With the prospect of power electronics technology and **, the switching power supply technology is constantly **, and this cost reversal point is increasingly moving to the low output power end, this provides a wide prospect space for switching power supply. High-frequency switching power supply is the direction of its prospect. High-frequency switching power supply is miniaturized and has entered a wider application field, especially in the field of high-tech, it has promoted the miniaturization and portability of high-tech products. In addition, the prospect and application of switching power supply are of great significance in security monitoring, energy conservation, resources conservation and environmental protection.
