The Main Transformer (>30kHz) collection is designed for high-frequency power conversion in applications requiring efficient AC-DC or DC-DC transformation. Operating at frequencies above 30kHz, these transformers are crucial for high-power applications such as electric vehicle chargers, renewable energy systems, and industrial power supplies. They offer high-efficiency power transfer, excellent voltage isolation, and compact designs, making them ideal for systems with space and thermal management constraints. Main transformers ensure stable operation, minimal energy loss, and are optimized for high-frequency switching, enhancing overall system performance.
