High-frequency transformers are magnetic components specifically designed for high-frequency power conversion circuits (with a working frequency above 20 kHz). They achieve voltage transformation, energy transmission, and circuit isolation through high-frequency alternating magnetic fields, and are the core components in modern power electronic devices such as switching power supplies, inverters, and new energy converters.
Compared with traditional power-frequency transformers, high-frequency transformers have the following notable features and advantages:
High efficiency and small size: According to the principle of electromagnetic induction, the higher the working frequency, the smaller the cross-sectional area of the magnetic core and the number of coil turns required to transfer the same power. Therefore, under the same power conditions, the volume and weight of high-frequency transformers can be more than one order of magnitude smaller than those of power-frequency transformers, achieving the miniaturization and lightweighting of power supply equipment.
Outstanding performance: The high-frequency design effectively reduces the hysteresis loss of magnetic materials and the eddy current loss of coils. Combined with low-loss magnetic core materials (such as ferrite, amorphous, and nanocrystalline) and twisted multi-strand wires like Litz wires, the overall energy conversion efficiency is extremely high.
Wide operating temperature range: The high-quality high-frequency transformer design is capable of adapting to harsh environments. For instance, it can operate within a temperature range of -40℃ to +125℃, ensuring stable operation under extreme high and low temperatures.
Wide application compatibility: Its operating frequency range is extensive (for example, from 20kHz to 500kHz), and the output power covers from 15W to 1000W and even higher, enabling flexible satisfaction of the requirements of different topologies (such as forward, reverse, LLC resonant) and power levels.
