The Two Major Categories of Switching Power Supplies
Stainless steel electric heating tube classification switch power supply mainly
In the field of switch mode power supply technology, people are developing related power electronic devices and switch frequency conversion technology at the same time. The two mutually promote and drive the development of switch mode power supplies towards the direction of light, small, thin, low-noise, high reliability, and anti-interference with an annual growth rate exceeding two digits. Switching power supplies can be divided into two categories: AC/DC and DC/DC.
Micro Low Power Switching Power Supply
Switching power supplies are moving towards popularization and miniaturization. Switching power supplies will gradually replace transformers in all applications in daily life. The application of low-power micro switching power supplies should first be reflected in digital displays, smart meters, mobile phone chargers, and other aspects. At present, the country is vigorously promoting the construction of smart grids, and the requirements for energy meters have been greatly increased. Switching power supplies will gradually replace transformers in the application of energy meters.
Reverse series switching power supply
The difference between a reverse series switching power supply and a general series switching power supply is that the output voltage of this reverse series switching power supply is a negative voltage, which is exactly opposite in polarity to the positive voltage output of a general series switching power supply; And because the energy storage inductor L only outputs current to the load when the switch K is turned off, under the same conditions, the current output of the inverted series switching power supply is twice as small as that of the series switching power supply.
