SEC-25KW-SIC-PIM-GEVK: Full SiC 25kW DC EV charger platform

SEC-25KW-SIC-PIM-GEVK is a reference design kit for 25kW fast DC EV charger based on SiC power integrated module. This full silicon carbide solution consists of PFC and DC-DC stages featuring multiple 1200V, 10m? half-bridge SiC modules (NXH010P120MNF1), the ultralow RDS(ON) and minimized parasitic inductance can significantly reduce conduction loss and switching loss. Relying on the powerful UCB, the system can deliver maximum 25kW over 200V-1000V output voltage with 96% all-time efficiency to charge 400V or 800V EV batteries.

SEC-25KW-SIC-PIM-GEVK also highlights the galvanic-isolated high-current driver NCD57000, auxiliary power solution SECO-HVDCDC1362-40W-GEVB to power stable voltage rails to low-voltage components, integrated protections like inrush control, over voltage protection and multiple interfaces for communication.
