The design principle of High Voltage Transformer is mainly based on the law of electromagnetic induction, which is a physical phenomenon that describes the interaction between magnetic and electric fields. Here is a brief explanation of how High Voltage Transformer converts low voltage to high voltage through the principle of electromagnetic induction:

Principle of electromagnetic induction: Electromagnetic induction describes the phenomenon that when a conductor or coil moves in a magnetic field, or when the magnetic field changes with time, an electromotive force (ie, voltage) is generated in the conductor or coil. This phenomenon was first discovered by Michael Faraday in 1831.

High Voltage Transformer structure: High Voltage Transformer is mainly composed of three parts: iron core, winding and casing. The iron core is stacked by multiple thin iron cores to reduce magnetic flux leakage and loss. The winding is divided into primary winding and secondary winding, which are connected to the input end and output end respectively. The casing protects the transformer from the external environment.

Working principle: When alternating current passes through the primary winding, an alternating magnetic field is generated in the iron core. This magnetic field passes through the secondary winding, causing an induced electromotive force in the secondary winding. According to Faraday's law of electromagnetic induction, the magnitude of the induced electromotive force is proportional to the rate of change of the magnetic field and the number of turns of the secondary winding.

To convert low voltage to high voltage, the transformer needs to be designed so that the secondary winding has far more turns than the primary winding. In this way, when the magnetic field changes in the iron core, the induced electromotive force generated in the secondary winding will be much higher than the electromotive force in the primary winding, thereby achieving an increase in voltage. At the same time, in order to maintain energy conservation, the current on the high-voltage side will be reduced accordingly.



In summary, High Voltage Transformer converts low voltage into high voltage through the principle of electromagnetic induction. The key is to achieve voltage transformation by adjusting the turns ratio of the primary and secondary windings. This design enables transformers to be used in a wide range of applications in power systems, such as power transmission, power distribution, and power conversion.
