Transformers for IGBT/FET
Tech Notes
TDK Product Features
Isolation transformers with high withstand voltages are required in the IGBT gate drive power supplies of motor inverters for xEVs. The products in this series successfully combine a shift to high coupling (low leakage) with a shift to completely automatic winding by employing a new structure that makes automatic winding possible, resulting in isolation transformers that can provide stable output. Even in terms of reliability, the separation of the connecting wire terminals for windings from the board connection terminals has yielded improvements in vibration resistance as well as highly-precise terminal flatness. Since their lineup now includes products ranging from single-output to 4-output types for vehicle-mounted applications, they are compatible with a wide variety of inverter board layouts.
