What is the main purpose of switching power supply? With the popularity of electrical equipment, switching power supply products are widely used, such as LED lighting, air purifiers, electronic refrigerators, liquid crystal displays and so on. Although we know these products, there are still many people who do not know what a switching power supply is, so what does a switching power supply mean? What is the working principle of a switching power supply?
What is the main function of switching power supply
Switching power supply is a kind of power supply that uses modern power electronic technology to control the time ratio of switching on and off to maintain a stable output voltage. Switching power supply is generally composed of pulse width modulation (PWM) control IC and MOSFET. With the development and innovation of power electronic technology, switching power supply technology is also constantly innovating.
At present, switching power supply is widely used in almost all electronic equipment because of its small size, light weight and high efficiency. It is an indispensable power supply method for the rapid development of today's electronic information industry.
What is the working principle of switching power supply? Switching power supply generally has three working modes: frequency, pulse width fixed mode, frequency fixed, pulse width variable mode, frequency, pulse width variable mode. The former working mode is mostly used for DC/AC inverter power supply, or DC/DC voltage conversion, and the latter two working modes are mostly used for switching regulated power supply.
The output voltage of the switching power supply also has three working modes: direct output voltage mode, average output voltage mode, and amplitude output voltage mode. Similarly, the former working mode is mostly used for DC/AC inverter power supply, or DC/DC voltage conversion, and the latter two working modes are mostly used for switching regulated power supply.
The above is what is the main function of the "communication power supply" switching power supply, and the working principle is all the content. Thank you for your browsing, you can bookmark the BWITT official website.
