Introduce high power DC/DC conversion design: comparison of PSFB and FB-LLC
This series compares phase shifted full bridge (PSFB) and full bridge LLC (FB-LLC) high power DC/DC converter topologies.
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.
