Product Introduction
A single-phase transformer is a device used for power transmission and voltage conversion, primarily for converting the voltage of alternating current from one level to another. It consists of two windings (primary winding and secondary winding) and an iron core. The primary winding is connected to the power supply, and the secondary winding is connected to the load.
###The basic principle of single-phase transformer:
1. Electromagnetic induction: When an alternating current passes through the primary winding, a changing magnetic field is generated in the iron core. The changing magnetic field will induce an electromotive force (voltage) in the secondary winding.
2. Transformation ratio: The relationship between the output voltage and input voltage of a transformer is determined by the turns ratio of the winding. The formula for transformer ratio is:
\[
\frac{V_s}{V_p} = \frac{N_s}{N_p}
\]
Among them\ (V_s \) is the secondary voltage\ (V_p \) is the primary voltage\ (N_s \) is the number of turns of the secondary winding\ (N_p \) is the number of turns of the primary winding.

###Attention:
-Efficiency: Transformers usually have high efficiency, but losses such as copper and iron losses still need to be considered.
-Overload protection: When using a single-phase transformer, its rated power should be considered to avoid overload.
-Cooling: Transformers generate heat during operation and require good heat dissipation design.
