The manufacturer of high-frequency transformer tells you the characteristics of high-frequency transformer

1 Operating frequency:
The core loss of transformer has a great relationship with the frequency, so it should be designed and used according to the use frequency, namely the working frequency.
2 Rated power:
Under the specified frequency and voltage, the transformer can work for a long time without exceeding the output power of the specified temperature rise.
3 Rated voltage:
It refers to the voltage allowed to be applied to the transformer coil, which shall not be greater than the specified value during operation.
4 Voltage ratio:
It refers to the ratio of primary voltage to secondary voltage of transformer, which is different from no-load voltage ratio and load voltage ratio.
5 No load current:
When the secondary of the transformer is open circuit, there is still a certain current in the primary, which is called no-load current. No load current consists of magnetizing current (magnetic flux generated) and iron loss current (caused by core loss). For a 50Hz power transformer, the no-load current is basically equal to the magnetizing current.
6 No load loss:
It refers to the power loss measured at the primary level when the secondary of the transformer is open circuit. The main loss is the iron core loss, followed by the loss (copper loss) caused by the no-load current on the copper resistance of the primary coil, which is very small.
7 Efficiency:
It refers to the percentage of the ratio of secondary power supply P2 to primary power supply P1. Generally speaking, the higher the rated power of the transformer, the higher the efficiency.
8 Insulation resistance:
It indicates the insulation performance between coils of transformer and between coils and iron core. The insulation resistance is related to the performance, temperature and humidity of the insulating materials used.
