Switching power supply manufacturers introduce switching power supply working principle

Switching power supply is the most common kind of equipment in our life, switching power supply is mainly applied in power electronics technology. It is controlled by the switching tube on and off the proportion of time. And thus can achieve a very good stabilization of the voltage output. General switching power supply is mainly used by the pulse width modulation control technology, with the development of technology the status quo of the switching power supply has become smaller and smaller, the use of which is more and more convenient, then the next small make up will give you the knowledge about the switching power supply, I hope to help you.

Switching power supply working principle

Switching power supply is generally composed of pulse width modulation (PWM) control IC and MOSFET. Switching power supply and linear power supply compared to the cost of both with the increase in output power and growth, but the rate of growth of the two are different. Linear power supply cost at a certain output power point, but higher than the switching power supply, this point is called the cost reversal point. With the development of power electronics technology and innovation, so that the switching power supply technology is also constantly innovating, this cost reversal point increasingly to the low output power end of the move, which provides a broad space for the development of switching power supply.

Switching power supply in the power electronics position is becoming more and more important, switching power supply is the main role of the proportion of time to control the switch on and off, and switching power supply is the biggest benefit is that it can make the output voltage more stable. With the development of switching power supply, it is also a very big change, now the switching power supply has become more and more compact, the quality is very light, the use of the efficiency is also very high, so the switching power supply in the electronics industry is widely used, while the switching power supply is also an indispensable power source for the development of electronic information engineering. For example, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, liquid crystal displays, industrial control equipment, communications equipment, power equipment, instrumentation, etc. are using switching power supply.
