As aviation equipment and military electronic systems continue to upgrade, airborne power supply systems must simultaneously meet multiple critical requirements, including ** high power density, high reliability, and adaptability to extreme environments**.
Many critical devices in modern aircraft, such as airborne radar, communication systems, and navigation systems, rely on a stable and reliable power supply.

In traditional power systems, 50Hz or 60Hz power frequency sources result in transformers with relatively large volumes and high weights due to their low frequency, which is not conducive to the miniaturization and lightweight design of aviation equipment.
Consequently, **400Hz medium-frequency power systems** have gradually become an important standard for aviation power systems, with 400Hz transformers serving as the critical core equipment for voltage conversion and electrical isolation within these systems.

By increasing the operating frequency, 400Hz transformers can
