1. Main circuit
Impact current limit: Limits the impact current on the input side when powered on. Input filter: Its function is to filter out the clutter present in the power grid and prevent the clutter generated by the machine from feedback back to the power grid. Rectification and filtering: The AC power supply of the power grid is directly rectified into smoother DC power. Inversion: Converts rectified direct current into high-frequency alternating current, which is the core part of high-frequency switching power supply. Output rectification and filtering: Provide stable and reliable DC power supply according to load requirements. The energy spent on the main circuit of the Minrong switching power supply is particularly high. It can be said that Minrong switching power supply has advantages such as high efficiency, high safety, and low losses, which cannot be separated from the contribution of the main circuit. Similarly, the high-quality main circuit of Minrong switching power supply cannot be separated from the deep technical support of Minrong Electric.

4. Auxiliary power supply
In the field of switching power supply technology, people are developing related power electronic devices, such as 320W single group switching power supply.
While developing switch frequency conversion technology, products and technology promote each other, promoting the development of switch power supplies towards light, small, thin, low noise, high reliability, and anti-interference, with an annual growth rate of over double digits. Switching power supplies can be divided into two categories: AC/DC and DC/DC.
Small low-power switching power supply
Switching power supply is developing towards miniaturization and popularization. Switching power supplies will gradually replace transformers in many applications in daily life. The application of low-power microswitched power supply should first be reflected in digital display meters, smart meters, mobile phone chargers, etc. At present, the country is vigorously promoting the construction of smart grids, and the requirements for energy meters have also been greatly improved. Switching power supply will gradually replace the application of transformers in energy meters. Some types and models of Minrong Electric switch power supplies have been developing in this direction. Minrong switch power supplies are known for their low losses and also have the characteristics of high efficiency, safety, convenience, and wide applicability. Its practicality in electricity meters is very strong, and the giant position of Minrong switching power supply in the market is becoming increasingly stable.
