The third generation DC/DC converter
The fuel cell-isolated boost DC-DC converter is used to convert the low-voltage DC boost of the fuel cell output into a high-voltage DC output, matching the voltage requirements of an electric vehicle, providing power to an electric vehicle while charging the power battery.The product has a power density of up to 5.3KW/L,resulting in a higher power density with minimal volume and increased economical utility. The low-pressure and high-pressure sides can withstand the pressure level of 3000Vdc, high insulation impedance, enhance the vehicle insulation impedance, improve vehicle safety.
Technical features
● SiC power device design;● High switching frequency, high power density, high efficiency;
● The company's third generation of new standard high power density, resonant soft switch technology, the use of more advanced circuit topology, digital control;
● Better dynamic adjustment capability to adapt to the large range of fluctuations in the load, to meet the requirements of vehicle mobility.
