PREMO offers a wide range of high-quality magnetics dedicated to the onboard battery chargers. Most of them are already AEC-Q200 fully qualified. High performances materials are used for the best efficiency, high temperature stability and reinforced insulation.
Our OBC kit contains:
EMI AC input filter common mode choke (iron powder, high permeability ferrite or nanocrystalline cores):
PFC chokes (different powder grades can be used for the core depending on the best compromise between saturation and losses)
Transformer and associated resonant chokes (custom optimized low-loss high-temperature stability ferrite cores, special insulated Litz wire, special connections)
Flyback auxiliary transformers (multi-outputs coupling and isolation management)
Gate-drive transformers for power switching semiconductors control (special techniques to ensure clearance & creepage distance requirements)
PLC transformer for communication (power line) between the charger and the charging point or to smart grid (galvanic isolation).
