Other Parts Discussed in Thread: UCD3138
We are working on BMS for 48V li-ion battery, therefore, we are evaluating the need of bidirectional DC/DC converter located on its input to control the battery current flow. Browsing Texas Instruments reference designs, we found PMP21529. Based on "4. Performance Specification" data located in the document "Test Report: PMP21529 4-Switch Buck-Boost Bi-directional DC-DC Converter Reference Design", this design intends to work with 2A in Battery Charge Mode and 10A in Backup Supply Mode.
Out intention is to rise its current capabilty to 100A on both directions.
I am not an expert on DC/DC converter topologies, so, I would like some guidance. Is it feasible to rise PMP21529 current capability just working on the hardware components and firmware parameters? Or is it better to implement such converter with a new topology, with higher efficiecy (altough this one has >95% efficiency)?
Many thanks in advance.
