Product Description

EE EFD ER EF high frequency transformer is a power transformer with a working frequency exceeding the intermediate frequency (10kHz), mainly used as a high-frequency switching power transformer in high-frequency switching power supplies, and also used as a high-frequency inverter power transformer in high-frequency inverter power supplies and high-frequency inverter welding machines. According to the working frequency, it can be divided into several levels: 10kHz-50kHz, 50kHz-100kHz, 100kHz-500kHz, 500kHz-1MHz, and above 10MHz.

The characteristics:

High frequency transformers have the characteristics of being thin, light, and short, making them suitable for use in high-frequency electronic devices. Due to its high operating frequency, it has the advantages of rapid transformation and high efficiency. However, high-frequency transformers also face some challenges, such as high winding losses, high temperature rise, and the need for special cooling measures.

Application scenarios of high-frequency transformers

High frequency transformers are widely used in high-frequency switching power supplies, high-frequency inverter power supplies, and high-frequency inverter welding machines. For example, in high-voltage frequency converters, high-frequency transformers can effectively isolate and transform voltage, improving system efficiency and reliability.
