The turn ratio of the transformer is the ratio of the transformer, that is, the turn ratio of the primary coil and the secondary coil. It reflects the ratio of the effective value of the voltage of the primary and secondary coils of the transformer. When the no-load current can be ignored, the effective value of the current of the primary and secondary coils is inversely proportional to its turns. The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, the secondary coil and the iron core.
Transformer transformation ratio is a device for transforming voltage or current. The voltage or current ratio between the primary winding and the secondary winding. In the transformer, the ratio of the primary side electromotive force E1 to the secondary side E2 is called the transformation ratio of the transformer. It is expressed in k, that is, k=E1/E2. The transformation ratio is a concept for calculating the error in the transformer design. Generally, when the transformation ratio is greater than 3, the error should be less than 0.5%; When the transformation ratio is less than or equal to 3, the error shall be less than 1%.
The windings of two groups of transformers are N1 and N2, N1 is the primary winding, and N2 is the secondary winding. When the AC voltage is applied to the primary winding, the induced electromotive force will be generated at both ends of the secondary winding. When N2>N1, the induced electromotive force is higher than the voltage applied to the primary winding. The multi-turn ratio is the corresponding relationship between the turns of the secondary winding with multiple outputs and the primary winding. The multi-turn ratio is to make one induction device used for various heat treatment processes.
