Slim Style Switch Power Supply
Switch Mode Power Supply (SMPS), also known as switching power supply and switching converter, is a high-frequency power conversion device and a type of power supply. Its function is to convert a level of voltage into the voltage or current required by the user through different forms of architecture. The input of the switching power supply is mostly AC power (such as mains power) or DC power, and the output is mostly equipment that requires DC power, such as personal computers. The switching power supply converts the voltage and current between the two.
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 cooling and heating, air purifiers, electronic refrigerators, liquid crystal displays, LED Lighting, communication equipment, audio-visual products, security monitoring, LED strips, computer cases, digital products and instruments.
In the field of switching power supply technology, people are developing related power electronic devices.

While developing switching frequency conversion technology, the two promote each other to promote the development of switching power supplies in the direction of light, small, thin, low noise, high reliability and anti-interference with a growth rate of more than two digits each year. Switching power supplies can be divided into AC / DC and DC / DC.
Miniature Low Power Switching Power Supply
Switching power supplies are moving towards popularity and miniaturization. Switching power supplies will gradually replace all applications of transformers in life. The application of low-power micro-switching power supplies must first be reflected in digital display meters, smart meters, mobile phone chargers and so on. At this stage, the state is vigorously promoting the construction of smart grids, and the requirements for energy meters have greatly increased. Switching power supplies will gradually replace the application of transformers on energy meters.
Reverse series switching power supply
The difference between an inverting series switching power supply and a general series switching power supply is that the voltage output by this inverting series switching power supply is a negative voltage, which has the opposite polarity to the positive voltage output of a general series switching power supply; The inductor L only outputs current to the load when the switch K is turned off. Therefore, under the same conditions, the current output by the inverting series switching power supply is less than the current output by the series switching power supply.
