Detailed explanation of the eight characteristics of high-frequency transformers
As an indispensable key component in modern electronic equipment, high-frequency transformers have many unique characteristics.
1. Working frequency
Rod inductors are enhanced versions of air-core inductors, and the inductance value is proportional to the magnetic permeability. The working frequency of high-frequency transformers is an important parameter for their design and use. Since the core loss of the transformer is closely related to the frequency, it is necessary to reasonably design the high-frequency transformer according to the specific frequency of use. Reasonable selection of the working frequency helps to improve the efficiency of the transformer and reduce energy consumption. , Put the magnetic material into the air-core coil, the inductance value, Q value, etc. will be greatly improved.
2. Rated power
Rated power refers to the output power that the transformer can work for a long time without exceeding the specified temperature rise under the specified frequency and voltage. Rated power is an important reference indicator in the design and use of high-frequency transformers. It determines the maximum output power of the transformer under normal working conditions.
3. Rated voltage
Rated voltage refers to the voltage allowed to be applied to the coil of the transformer, which shall not be greater than the specified value during operation. The rated voltage is the guarantee for the safe operation of the high-frequency transformer. Exceeding the rated voltage may cause damage to the transformer or cause a safety accident.
4. Voltage ratio
The voltage ratio refers to the ratio of the primary voltage to the secondary voltage of the high-frequency transformer. The voltage ratio is divided into no-load voltage ratio and load voltage ratio, both of which have their own characteristics in practical applications. The voltage ratio is a key parameter for high-frequency transformers to achieve voltage conversion, and is of great significance for the stable operation of electronic equipment.
