Ask : Does the power of the ring high frequency transformer depend on the size of the iron core or the diameter of the wire?
Answer:
The size of the core, in other parameters (such as a certain switching frequency), the greater the power, the larger the transformer core.
Line diameter is related to the size of the current. When designing high-frequency transformers, the general current density is 3~5A/ mm square. Obviously, the larger the current is, the thicker the line is required.
But the magnitude of the current is not necessarily related to the power.
