Ⅰ. What is a transformer?


The transformer is a crucial electrical device that operates on the principle of electromagnetic induction. It consists of two interlinked coils, which transform electrical energy into magnetic field energy to adjust voltage levels. When one coil receives alternating current, it generates an alternating magnetic field. This field alters the magnetic flux in the second coil, inducing an electromotive force. This mechanism facilitates the transmission and distribution of electrical energy, ensuring a dependable and steady power supply for diverse equipment.

Therefore, when designing electronic systems, we must fully consider the effects of low cross-coupling and noise to ensure the stability and reliability of data transmission.



Ⅵ. Working principle of H1102NL


H1102NL, a magnetic transformer, comprises the primary coil and the secondary coil, constructed from insulated wires coiled around each other. In communication equipment, for signal transmission between locations, the input signal is typically linked to the primary coil, and the output signal is typically linked to the secondary coil. The flow of current through the primary coil generates a magnetic field within it.


According to Faraday's law of electromagnetic induction, when the current in the primary coil changes, it induces a voltage in the secondary coil. The working principle of the transformer is based on this principle, changing the voltage and current of the output signal by controlling the current changes in the main coil. This allows the transformer to be used for signal transmission, isolation, impedance matching and other electronic applications.
