What is a switching power supply?

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.

What is the application scope of switch power supply? 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.

What is the structure of switch power supply products?

Roughly by the main switch power supply circuit, control circuit, detection circuit, auxiliary power supply of the four most.

Switching Power Supply Common faults:

1.Blown fuse.
2.No dc voltage output or the output voltage is not stable.
3.The power load ability is poor.
