Introduce high power DC/DC conversion design: comparison of PSFB and FB-LLC
Comparing Phase Shifted Full Bridge and Full Bridge LLC high power DC/DC converter topologies, and which is the best choice for a given application.
The “conventional wisdom” is that the Phase Shifted Full Bridge (PSFB) topology is the best choice for high power DC/DC converter applications. However, the “conventional wisdom” has been challenged by the users who are choosing the Full Bridge LLC (FB-LLC) topology for applications where we would normally suggest the PSFB topology. The speaker provides a clear comparison between the two typologies and tries to indicate which is best in a given application.
