6.6kW OBC Evaluation Board using Totem Pole Topology based on onsemi Solution
This 6.6kW OBC evaluation board provides a reference design on the power stage of totem pole interleave PFC topology which consists of 650V N-Channel Power MOSFET SUPERFET III (NVHL025N65S3), monolithic high- and low-side gate-driver IC (FAN7191_F085) in low-speed leg, high switching performance SiC MOSFET (NVHL060N090SC1), Isolated High Current and High Efficiency IGBT driver (NCV57000DWR2G) in high-speed leg. With these high performance devices and totem pole topology, the system efficiency reaches 97% (typical value), and hardware protection of OCP and OVP is also provided for high system reliability.
