What is switching power supply?

With the development and innovation of power electronic technology, switching power supply technology is also constantly innovative. At present, switching power supply is widely used in almost all electronic equipment with the characteristics of small size, light weight and high efficiency. It is an indispensable power supply mode for the rapid development of electronic information industry.
Switching power supply is a kind of power supply which uses modern power electronic technology to control the time ratio of switching on and off to maintain stable output voltage. The switching power supply is generally composed of pulse width modulation (PWM) control IC and MOSFET.
Switching power supply is a relatively linear power supply. Its input end directly rectifies alternating current into direct current, and then under the action of high-frequency oscillation circuit, the switch tube is used to control the on-off of the current to form high-frequency pulse current. With the help of inductor (high frequency transformer), stable low voltage
