Electronic transformers are core components of power supply, electronic, and communication equipment. Based on the principle of electromagnetic induction, they transmit electrical energy between circuits, converting alternating current (AC) into AC of different voltages. They realize voltage transformation, impedance matching, electrical isolation, and signal transmission, serving as key devices for equipment to adapt to power supply conditions.
Electronic transformers can be classified by core, frequency and installation method. Among them, EE19, EF20, PQ and EFD transformers are the mainstream types. The EE19 power switch high frequency transformer has a symmetrical structure and a stable magnetic circuit
The EF20 transformer is compact in size and has a high coupling efficiency.Mobile phone charger EF20 transformer, USB PD adapter and other consumer power equipment, is the core components of small power fast charging
The PQ50 transformer has strong power carrying capacity and low leakage flux. PQ50 industrial switching power supply transformers, DC-DC converters and other equipment. It has a high insulation resistance, can resist the interference of industrial dust, and ensure the stable conversion of high-power electrical energy.
The EFD20 transformer has a flat and thin design, suitable for high frequency working conditions. High-frequency transformers are also mainstream choices for current electronic devices, applicable to smart sockets, small sensors, etc. According to mounting methods, they are divided into through-hole type and surface-mount type to meet different production process requirements.
