Switching power supply is the use of modern power electronic technology, control switch tube opened and shut off time ratio, to maintain stable output voltage of a power supply, switching power supply by general pulse width modulation (PWM) control IC and MOSFET. With the development of power electronic technology and innovation to make switching power supply technology is also in constant innovation. Currently, switching power supply with the characteristics of small, light weight and high efficiency are widely used almost all electronic devices, is the rapid development of electronic information industry indispensable to a way of power supply.
 
With the rapid development of power electronics technology, power electronic devices and is closely related to people's work and life, and the electronic equipment is inseparable from the reliable power supply, into the 80 s is made up of the computer power supply switch power supply, power generation, the first complete computer into the switch power supply in the 90 s have entered various electronic, electrical equipment, program-controlled switches, communications, electronic test equipment such as power supply, control equipment power supply has been widely used for switching power supply, promote the rapid development of the technology of switching power supply.
 
Switch power supply and linear power supply, compared to the cost of both increased with the increase of output growth, but the growth rate of each different. Linear power supply cost on a power output point, rather than switching power supply. With the development of power electronic technology and innovation to make switching power supply technology in constant innovation, the cost of reversal points increasingly move to low output power end, for the switching power supply provides a broad space for development.
 
High frequency switch power supply is its development direction, high frequency, the miniaturization of switch power supply, switching power supply and to enter into a wider range of applications, especially in the high and new technology in the field of application, promoted the high-tech products of miniaturization, light change. In addition the development and application of switch power supply in security monitoring, saving energy, saving resources and protecting the environment is of great importance.
 
The main purpose
 
Switching power supply products are widely used in industrial automation control, military industry equipment, scientific research equipment, LED lighting, industrial control equipment, communications equipment, electrical equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifier, electronic refrigerator, LCD, LED lamps and lanterns, communications equipment, audio and video products, security monitoring, leds bags, computer case, digital products and instruments, etc.
