MOSFET power module is a combination of certain functions and modes. MOSFET power module is a combination of high-power electronic and electric devices with certain functions and then sealed into a whole. The MOSFET power module can achieve different functions according to the different encapsulated components.
Chongqing Pingchuang has developed and pre-developed many SiC MOSFET modules, including 650V 60A module, 1200V 20A/40/450A module, 1700V 25A/200A/225A module. The silicon carbide power module is based on chip products, according to customer needs, multi-chip combination integration of functional components.
SiC Schottky barrier diodes (SiC SBD) have a small total charge (Qc), low switching loss and high switching speed. SiC SBDs are used to improve the reliability of power conversion systems, such as battery charging, charging circuits for electric and hybrid vehicles, and solar panels.
SiC MOSFET has a substantial advantage in conduction losses, particularly at lower power outputs. Combining this switching-loss reduction with the lower overall conduction losses, it is clear that the SiC switch is a much more efficient device for high-power-conversion systems.
