The high-frequency transformer is a power transformer with a working frequency exceeding the intermediate frequency (10 kHz). It is mainly used for high-frequency switching power supply transformers in high-frequency switching power supplies, and also for high-frequency inverters in high-frequency inverter power supplies and high-frequency inverter welding machines. Variable power transformer. According to the working frequency, it can be divided into several grades: 10kHz - 50kHz, 50kHz - 100kHz, 100kHz ~ 500kHz, 500kHz ~ 1MHz, 10MHz or more.
Ee13 flyback switching transformers are commonly used in mobile phone chargers, DC-DC converters, drive transformers, digital cameras, handheld switching power supply chargers, etc.
A transformer is a device that converts alternating voltage, current, and impedance. When an alternating current is passed through the primary coil, an alternating magnetic flux is generated in the iron core (or core) to induce a voltage (or current) in the secondary coil. The transformer consists of a core (or core) and a coil. The coil has two or more windings. The winding connected to the power supply is called the primary coil, and the other winding is called the secondary coil.
