Chip power inductors, this type of chip inductors is also called power inductors, high current inductors. SMD inductance is an attribute of closed loop. When the coil of the chip inductor passes current, the chip inductor forms a magnetic field induction in the coil, and the induced magnetic field generates an induced current to resist the current passing through the coil. The role of the chip inductor in the circuit is to generate a changing magnetic field when passing an unstable current, and this magnetic field will in turn affect the current. The chip inductor is like an inductor in the power circuit, and the inductor is direct to DC , It is high resistance to high frequency pulse, so it plays the role of DC resistance to AC pulse.

Chip inductors are electromagnetic induction components made of insulated wires. It is a common sense element. The role of chip inductors: AC through DC resistance, which is a simple way of saying that AC signals are isolated, and the filter or resonance circuit is composed of capacitors and resistors. Inductance tuning and frequency selection function: the inductor coil and the capacitor are connected in parallel to form an LC tuning circuit. Any current in the chip inductor in the circuit will generate a magnetic field, and the magnetic flux of the magnetic field acts on the circuit.
When the current flowing through the chip inductor changes, the DC voltage potential generated in the chip inductor prevents the current from changing. When the current through the inductor increases, the self-induced electromotive force and the current generated by the inductor decrease. When the current through the inductor decreases, the self-induced electromotive force and the current direction are the same to prevent the current from decreasing, and release the stored energy to compensate for the decrease in current. The direction of the current is opposite to prevent the current from increasing and convert a part of the electric energy into a magnetic field. The magnetic field can be stored in the inductor. Therefore, after inductance filtering, it not only reduces the load current and voltage pulsation, but also increases the conduction angle of the rectifier diode. .
