EI66 Electronic Transformer Isolation Audio Transformer

Audio transformer belongs to low frequency

Since the frequencies of high frequency and low frequency are different, the high frequency can only be used in the circuit with high frequency and the frequency of the excitation source matches the frequency of the transformer, while the low frequency can not be mixed, even if the frequency of high frequency is not matched, it can not be used generally.

If a transformer transmits a certain amount of energy, has a high operating frequency, transmits energy many times in a certain time, and transmits less energy each time, the transformer uses less materials and has a small structural size. Therefore, the coil turns of a general high-frequency transformer are relatively small, and the size can be very small. The coil turns of a low-frequency transformer are relatively large.

For the two types of transformers with the same power, the high-frequency transformer will be much smaller than the low-frequency transformer. In this case, the high-frequency transformer will only be about one tenth of the low-frequency transformer. This is because the low-frequency transformer needs to be protected to reduce the U value. It is made of silicon steel sheet, but the efficiency becomes poor, so it needs to do large-scale heat dissipation.
