High-power electronic power devices are repotted into an integrated module according to a certain combination of functions.
A power semiconductor module is a combination of certain functions and modes, and a power semiconductor module is a high-power electronic power device that is re-potted into a whole according to a certain function combination. Power semiconductor modules can achieve different functions according to the different components in the package. Power semiconductor modules can be used as air-cooled modules with air-cooled heat dissipation, and water-cooled modules with water-cooled heat dissipation.
It is characterized by simple installation, convenient use and maintenance, small size and light weight.
Typical applications in AC/DC motor control, various rectifier power supplies, industrial heating control, dimming, non-contact switches, electric welding machines, motor soft start, reactive power compensation, frequency converters, UPS power supplies, battery charging and discharging, etc.
