The relationship is introduced between power and frequency and core of high frequency transformer 

What is the relationship between high frequency transformer power and frequency and iron core?

The power approximation of high frequency transformer is in direct proportion to core capacity and core cross-sectional area, 

ac frequency and core magnetic density,Actual output power

It's related to the wire diameter, and it's proportional to the size of the core window. With equation

Formula forWindow size * core area = (output power * traverse current)/(a coefficient * ac frequency * core magnetic density),

This formula is more accurate. Another common but less accurate formula is (core cross-section area x magnetic density x lamination coefficient) squared

For the standard EI core, in the first formula, the window size is the same as the iron core cross-section area, and for the power frequency alternating 

current, it becomes

The second formula,Both of these formulas are empirical.

What is the relationship between transformer power rate and frequency

Suppose we are talking about a transformer, as is commonly known, whose core is made of a cold-rolled silicon steel sheet with high magnetic conductivity.

 Under this condition:

Frequency increase: the magnetic flux density in the core decreases proportionally, but under the same magnetic flux density, the higher the frequency, 

the greater the unit loss of the core.

When the two are combined, the result is a higher frequency and a lower unit loss of the core.

Core loss is the reduction of no-load loss.

Transformer efficiency A= output power P2/ input power P1= (input power P1- no-load loss P0- load loss PK)/ input power P1= (p1-p0-pk)/P1

Therefore, if other conditions remain unchanged, the frequency is increased. As the no-load loss P0 decreases and the output power P2 increases, 

the efficiency of the transformer increases.

The power of the transformer is related to the section area of iron core and the diameter of copper wire. The larger the section area is, the larger 

the window space is and the larger the diameter of copper wire is.

Transformer labeled 4 w, its core column cross-sectional area: S = 1.25 * square root of P = 1.25 * square root of 4 = 2.5 ㎡ (c)
