Why high frequency transformer is small in size?
1 Answers
The size of the high-frequency transformer is small because it operates at high frequency, let me explain.
E = 4.44fNQm
B = Qm / AÂ Â Â Â A means area
E = 4.44fNBA
Therefore, f = 1 / A
The frequency is inversely proportional to the area. If the frequency increases the area will reduce.
