The influence of current on the magnetic rod inductance coil
Isolate and reduce the AC signal or form a resonant circuit with resistors, capacitors, etc. Tuning and frequency selection inductance: Inductance coil and capacitor in parallel can form an LC tuning circuit. That is, the natural oscillation frequency 0 of the circuit is equal to the frequency of the non-AC signal, and the inductance and capacitance of the loop are also equal, so the electromagnetic energy oscillates back and forth between the inductance and the capacitance, which is the resonance phenomenon of the LC loop. During resonance, the capacitive reactance and inductive reactance of the circuit are reversed, so the total reactance of the loop current is small, and the amount of current (refers to an AC signal of -0). Therefore, the LC resonant circuit has the function of selecting frequency and can The frequency AC signal is selected.
The effect of current on the shielding signal of the magnetic inductance coil?
It can be understood that the reason why the magnetic rod inductance coil is so large, manufacturers all know that the higher the signal frequency, the easier it is to radiate out, and the general signal lines are not shielded, these signal lines become very A good antenna receives various messy high-frequency signals in the surrounding environment. However, these signals are superimposed on the original transmitted signal, and even change the original transmitted useful signal, which seriously hinders the normal operation of electronic equipment, thus reducing the electromagnetic of electronic equipment. Interference (EM) is already an issue that must be considered. Under the action of the magnetic ring inductance, even if the normal and useful signals pass smoothly, it can well suppress high-frequency interference signals, and the cost is low. The role of the magnetic rod inductance coil also has excessive noise, screening signals, stable current and Suppresses important effects such as electromagnetic wave dry wiping.
