110 to 24 volt transformer7/30/2023 When the secondary side of the transformer is open, that is, when the transformer is no-load, the voltage at the primary and secondary terminals is proportional to the number of turns of the primary and secondary windings. The voltage on the side with more winding turns is higher, and the voltage on the side with less winding turns is lower. Its magnitude is proportional to the number of winding turns and the maximum value of the main magnetic flux. The specific process is when an AC voltage U1 is applied to the primary side of the electrical transformer, and the current flowing through the primary winding is I1, the current will generate alternating magnetic flux in the iron core, which makes the primary winding and the secondary winding electromagnetically connections.Īccording to the principle of electromagnetic induction, the electromotive force will be induced when the alternating magnetic flux passes through these two windings. Transformer mainly uses the principle of electromagnetic induction to work. ![]() ![]() The winding connected to the power supply is called the primary winding, and the remaining windings are called the secondary winding. It is composed of an iron core and a coil. When an AC current is passed through the primary coil, an AC magnetic flux is generated in the iron core, causing a voltage (or current) to be induced in the secondary coil. ![]() It can be designed to step up or step down voltages and works on the magnetic induction principle. A transformer is an electrical apparatus designed to convert alternating current from one voltage to another.
