High-frequency transformers operate at switching frequencies above 20 kHz, enabling compact, efficient power conversion in switch-mode power supplies, converters, and inverters. Their ferrite cores minimize eddy current losses. These transformers are essential for modern electronics-from phone chargers to renewable energy systems-delivering reliable isolation, voltage regulation, and high power density in small form factors.
