Transformers are a common type of equipment in the electrical field, widely used in infrastructure, factories, homes, and other fields. It is an electrostatic device that can convert high voltage to low voltage or low voltage to high voltage. Its working principle is based on Faraday's law of electromagnetic induction, which means that when a changing current is applied in a closed circuit, an electromotive force is induced in another circuit. The transformer utilizes this principle to change the magnetic flux by transferring current in the winding, thereby transferring the power of the input voltage to the output circuit.
The basic principle of a transformer is to apply input voltage to the primary winding, and the current in the primary winding flows into the magnetic core and generates a magnetic field. This magnetic field induces the electromotive force in the secondary winding, thereby generating an output voltage in the secondary winding. The size of the voltage is related to the proportion of the winding, usually using the proportion of the transformer's winding to adjust the output voltage. If the winding ratio of the secondary winding is higher than that of the primary winding, the output voltage will be higher than the input voltage; If the winding ratio of the secondary winding is lower than that of the primary winding, the output voltage will be lower than the input voltage.
