How an inductive coil works
Inductance coil is an electromagnetic induction element made of insulated wire. It is a common inductance element.The role of the inductor coil: through dc resistance ac this is a simple way of saying that the ac signal isolation, filtering or with capacitors, resistors and other components of the resonant circuit;The role of tuning and frequency selective inductance: inductance coil and capacitor in parallel can form LC tuning circuit.Any current passing through an inductive coil in a circuit creates a magnetic field, and the magnetic flux of the field ACTS on the circuit.
When the current through the inductor coil changes, the dc voltage potential generated in the inductor coil will prevent the current from changing: when the current through the inductor coil increases, the self-induced electromotive force generated by the inductor coil is opposite to the current, preventing the current from increasing;When the current passing through the inductor is reduced, the self-induced electromotive force moves in the same direction as the current, preventing the current from decreasing and releasing the stored energy to compensate for the reduced current.Therefore, after inductance filtering, not only the pulsation of load current and voltage decreases, the waveform becomes smooth, but also the conduction Angle of rectifier diode increases.
