About the switching power supply:
Switching power supply is a kind of power supply that uses modern power electronics technology to control the time ratio of switch on and off to maintain a stable output voltage. Switching power supply is generally composed of pulse width modulation (PWM) control IC and MOSFET.
Switching power supply is said to be relatively linear power supply, its input end directly rectifies AC power into DC power, and then under the action of high-frequency oscillation circuit, the switching tube is used to control the on and off of the current to form high-frequency pulse current. With the help of an inductor (high-frequency transformer), a stable low-voltage direct current is output.
