Silicon carbide (SiC) semiconductor has attracted the attention and research of many enterprises because of its significant advantages such as high frequency, low loss and high reliability. In rail transit systems, the application of silicon carbide devices helps to improve the overall efficiency of the traction / auxiliary system, reduce the energy consumption, reduce the volume and weight, and improve the reliability of the system. Based on the current market demand and more than 30 years of experience in research and development, Huasi company upgrades and iterates the existing products of the enterprise, and the silicon carbide charger module developed by silicon carbide devices emerged at the right moment.

The 15kW silicon carbide charger independently developed by the company has many advantages of small size, low loss, high efficiency and low noise. It adopts standardized, scalable design principles, so that the product has high flexibility and adaptability, can meet the needs of multiple scenarios, such as new energy, rail transit, construction machinery and vehicles and other fields. The charger has high reliability and strong thermal circulation ability at high temperature and high frequency. Compared to the traditional silicon devices, it can improve the overall product efficiency to 95%.

product function:

High efficiency conversion: using full SiC devices, topology using soft switching technology and synchronous rectification technology, the efficiency of this charger is up to 95% under rated input and output conditions, far exceeding the traditional scheme charger, greatly reducing energy consumption and improving energy utilization efficiency.

Safe and reliable: The digital control system based on DSP, combined with the dual protection mechanism of semiconductor Desat protection and power circuit (software comparison and hardware comparison), ensures the stable operation of the charger under various working conditions. At the same time, the rich protection functions (such as input undervoltage, overcurrent, intermediate bus overvoltage, overcurrent, output overvoltage, overcurrent, overload, radiator overtemperature, etc.) to further improve the safety and reliability of the equipment.

Design lightweight and convenience: Through lightweight design, this charger maintains high power density while reducing the overall weight and easy installation and maintenance. The external interface of power, control and auxiliary power supply are designed with plug and plug terminals, which simplifies the wiring process and improves the installation efficiency.

Intelligent charging management: with constant voltage and constant current charging functions, it can adjust the charging strategy automatically according to the battery state, prolong the battery life, and improve the charging efficiency.
