[0002] A high-frequency transformer is a power transformer with an operating frequency exceeding the medium frequency (10kHz). It is mainly used as a high-frequency switching power supply transformer in a high-frequency switching power supply. It is also used as a high-frequency inverter power supply transformer in a high-frequency inverter power supply and a high-frequency inverter welding machine.
