U.S. Switching Power Supply Manufacturers

By reducing the operating current and junction temperature, the stress of the device can be reduced and the reliability of the product can be greatly improved.

Modularization is the general trend of the development of switching power supply.

Distributed power supply system can be composed of modular power supply, N+1 redundant power supply system can be designed, and the capacity expansion of parallel mode can be realized.

In view of the disadvantage of high operating noise of switching power supply, if high frequency is pursued alone, its noise will also increase.

The partial resonance conversion circuit technology can theoretically achieve high frequency and reduce noise.

However, there are still technical problems in the practical application of partial resonance conversion technology, so a lot of work still needs to be done in this field to make many technologies practical.
