The traction transmission system is one of the most critical components in high-speed trains. SiC diode modules can be used in inverters, DC/DC converters and other circuits in traction transmission systems to improve the efficiency and reliability of traction motors.
- Auxiliary power system
High-speed trains require a large amount of power to support their operation, and they also need to provide stable power for various equipment. SiC diode modules can be used in rectifiers, DC/DC converters and other circuits in auxiliary power systems to improve the stability and efficiency of the power supply.
- Brake system
The braking system of high-speed trains is crucial to guarantee the safe operation of the trip. SiC diode modules can be used in inverters, DC/DC converters, and other circuits in the braking system to improve its efficiency and reliability.
