Structure and principle of switching power supply

Switching power supply can be seen locally for many years. It is an indispensable power supply method in our modern information industry. Switching power supply is a kind of power supply that uses modern power electronics technology to control the timing ratio of switch tube registration and off, and insists on stable output voltage.

In the linear power supply, the power transistor is working, and the linear power supply is PWM switching power supply that causes the closing or opening. In the closing and opening conditions, the voltage of the power transistor is relatively small, which will produce a large current. When the switching power supply is closed, it is the reverse. The voltage is large, and the current will be particularly small. The controller that controls the operating principle of the switching power supply, It is to be able to better adhere to stability and bring safety to people's living environment.
