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.
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).
