mmssm said:A secondary textbook said that if there is no flux leakage,
Vp/Vs=Np/Ns, no matter what is the efficiency of the transformer. May I know will the ohmic loss and eddy current contribute to the loss and modify the voltage ratio? thanks!
The efficiency of a transformer is directly affected by its turn ratio. This is because the turn ratio determines the voltage ratio between the primary and secondary coils, which in turn affects the amount of power loss in the transformer.
A higher turn ratio results in a higher voltage ratio, which means that more power is transmitted through the transformer. This can also lead to higher power losses and decreased efficiency.
The ideal turn ratio for maximum efficiency in a transformer varies depending on the specific design and purpose of the transformer. However, in general, a lower turn ratio is preferred as it results in a lower voltage ratio and therefore lower power losses.
Yes, the turn ratio of a transformer can be adjusted by changing the number of turns in the primary and secondary coils. By decreasing the turn ratio, the efficiency of the transformer can be improved.
The material used in a transformer can affect its turn ratio and efficiency in several ways. For example, using a material with higher electrical conductivity can decrease the resistance and power losses in the transformer, resulting in a higher efficiency. Additionally, different materials may have different magnetic properties, which can also impact the turn ratio and efficiency of the transformer.
