Switching power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers. . . .
Switching power supply products are widely used in industrial automation control, military equipment, scientific research equipment, LED lighting, industrial control equipment, communication equipment, power equipment, instrumentation, medical equipment, semiconductor refrigeration and heating, air purifiers, electronic refrigerators, liquid crystal displays, LED Lighting, communication equipment, audio-visual products, security, computer chassis, digital products and instruments.
With the rapid development of power electronics technology, the relationship between power electronic equipment and people's work and life is increasingly close, and electronic equipment is inseparable from reliable power supply. In the 1980s, computer power "target=_blank> machine power supply fully realized the switch. Power supply, the first to complete the power generation of the computer, into the 90s, switching power supply has entered a variety of electronic and electrical equipment fields, program-controlled switches, communications, electronic testing equipment power, control equipment power supply, etc. have been widely used switching power supply, and promoted The rapid development of switching power supply technology is a kind of power supply that uses modern power electronics technology to control the ratio of the turn-on and turn-off of switching transistors to maintain a stable output voltage. Switching power supplies are generally controlled by pulse width modulation (PWM) and The MOSFET is composed. Compared with the linear power supply, the cost of both the switching power supply increases with the increase of the output power, but the growth rate of the two is different. The linear power supply cost is higher than the switching power supply at a certain output power point. This cost reversal point. With the development and innovation of power electronics technology, Switching power supply technology continually innovation, increasing the cost of the reversal point moves to the low output power side, which provides a wide development space for the switching power supply.
The high frequency of switching power supply is the direction of its development. The high frequency makes the switching power supply miniaturized, and the switching power supply enters a wider range of applications, especially in the high-tech field, which promotes the miniaturization and lightness of high-tech products. Turn. In addition, the development and application of switching power supplies are of great significance in terms of energy conservation, resource conservation and environmental protection.
