The main classifications of switch power supplies.
Author:
In the field of switch power supply technology, people are developing related power electronic devices while simultaneously developing switch frequency conversion technology. The two mutually promote each other, driving the switch power supply to grow at a rate exceeding double digits each year, moving towards being lighter, smaller, thinner, lower noise, more reliable, and more resistant to interference. Switch power supplies can be divided into two main categories: AC/DC and DC/DC.

Micro low-power switch power supply
Switch power supplies are becoming more popular and miniaturized. They will gradually replace transformers in all applications in daily life, with the application of low-power micro switch power supplies first reflected in digital displays, smart meters, mobile phone chargers, and so on. At this stage, the country is vigorously promoting the construction of smart grids, significantly raising the requirements for electric energy meters, and switch power supplies will gradually replace transformers in the application of electric energy meters.
Inverted series switch power supply
The difference between the inverted series switch power supply and the general series switch power supply is that the output voltage of this inverted series switch power supply is negative, which is exactly opposite to the positive voltage polarity output by the general series switch power supply; and since the energy storage inductor L only outputs current to the load when the switch K is turned off, under the same conditions, the output current of the inverted series switch power supply is half that of the series switch power supply.
