Chip inductors are electromagnetic induction components wound with insulated wires. It is a commonly used inductive element. The role of the chip inductor: pass DC resistance AC This is a simple statement, isolate the AC signal, filter or form a resonant circuit with capacitors, resistors, etc. The role of tuning and frequency selection inductors: the inductor coil and capacitors can be connected in parallel to form LC Tune the circuit.

Any current of the chip inductor in the circuit will generate a magnetic field, and the magnetic flux of the magnetic field will act on the circuit.

When the current passing through the chip inductor changes, the DC voltage potential generated in the chip inductor will prevent the current from changing. When the current passing through the inductance coil increases, the self-inductive electromotive force generated by the inductive coil is the same as the electric current. When the current passing through the inductive coil decreases, the self-inductive electromotive force is in the same direction as the current, preventing the decrease of the current and releasing the stored energy at the same time. Compensate for the reduction in current.

The flow direction is opposite, preventing the increase of the current, and at the same time converting a part of the electric energy into a magnetic field that can be stored in the inductance; therefore, after the inductance filtering, not only the pulsation of the load current and voltage is reduced, the waveform becomes smooth, and the conduction of the rectifier diode angle increases.
