What Do You Know about Switching Power Supply?

Date:2021.02.05   Views:536

Switching power supply is a power supply that uses modern power electronics technology to control the time ratio of switching tube turn-on and turn-off to maintain a stable output voltage. Switching power supplies are generally composed of pulse width modulation (PWM) control ICs and MOSFETs. With the development and innovation of power electronics technology, making switching power supply technology is also constantly innovating. At present, switching power supply is widely used in almost all electronic devices with the characteristics of small size, light weight and high efficiency, and is an indispensable power supply method for the rapid development of today's electronic information industry.Switching power supply supplier will explain the main uses and types of switching power supply

The main uses of switching power supply

Switching power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, electric power equipment, instruments and meters, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, LCD monitors, LED lamps and lanterns, communication equipment, audio-visual products, security monitoring, LED light strips, computer chassis, digital products and instruments, etc.

Switching Power Supply

The Main types of switching power supply

There are two types of modern switching power supplies: one is DC switching power supply; the other is AC switching power supply.

The main introduction here is only DC switching power supply, whose function is to convert the original power supply (coarse power) of poor power quality, such as utility power or battery power, into a higher quality DC voltage (fine power) to meet the requirements of the equipment. The core of a DC switching power supply is the DC/DC converter. Therefore, the classification of DC switching power supplies is dependent on the classification of DC/DC converters. In other words, the classification of DC switching power supplies is basically the same as the classification of DC/DC converters, and the classification of DC/DC converters is basically the classification of DC switching power supplies.

DC DC/DC converters can be divided into two categories according to whether there is electrical isolation between the input and output: one is called isolated DC/DC converter with isolation; the other is called non-isolated DC/DC converter without isolation.
