High Amperage Boost Converter Design
High Amperage Boost Converter Design
(OP)

This popular boost converter design. Is this an acceptable design to boost 48V up to 170V with 100 amp output? Or, is there a more accepted design for this type to DC step up?

Here are just a few suggestions for study: A single full-bridge using one of those Infineon water-cooled bridge modules, Multiple SMPS all tied together such as: multiple full bridge, half bridge, or auto transformers.

Besides a multiphase/interleaved boost (and likely 8+ phases) I would consider using multiple 2-switch forward converters or a single current-mode push-pull. The latter two choices especially if isolation between the 48V and 170V sides is needed.
