SEC-25KW-SIC-PIM-GEVK: Full Silicon Carbide 25kW DC EV Charger Platform

SEC-25KW-SIC-PIM-GEVK is a 25kW fast DC electric vehicle charger reference design kit based on SiC power integrated modules. This full SiC solution consists of PFC and DC-DC stages, with multiple 1200V, 10mohm half-bridge SiC modules NXH010P120MNF1, ultra-low RDS(ON) and minimized parasitic inductance can significantly reduce conduction and switching losses. Relying on a powerful universal controller board (UCB) and Zynq®-7000 SoC FPGA and ARM®-based processor, the system can provide a maximum of 25kW of power at an output voltage of 200V-1000V, with a full-time efficiency of 96%, and can charge 400V or 800V electric vehicle batteries. The SEC-25KW-SIC-PIM-GEVK also highlights the galvanically isolated high current driver NCD57000, auxiliary power solution SECO-HVDCDC1362-40W-GEVB for providing stable voltage rails for low voltage components, integrated protection features such as surge control, overvoltage protection, and multiple communication interfaces.
