Applying EMI mitigation techniques in battery management systems (BMS) in
electric vehicles can help engineers not only easily meet CISPR 25 Class 5
EMI standards but also increase power density, and lower BOM count and
overall system cost. This video demonstrates how the UCC12051-Q1 DC/DC bias
supply module can help provide a power-dense solution with excellent EMI
performance through customized integrated transformer, switching frequency
dithering and added ceramic ycap, and provides conducted and radiated EMI
test results.
