What Is a Power Inductor?

SMD power inductors, also known as power inductors, high current inductors. SMD inductor is a property of closed loop. When the coil of the chip inductor passes a current, the chip inductor forms a magnetic field induction in the coil, and the induced magnetic field will generate an induced current to resist the current flowing in the coil. The role of the chip inductor in the circuit is to generate a changing magnetic field when passing an unsteady current, and this magnetic field will in turn affect the current. The chip inductor is like a inductor in the power circuit. It is high-impedance for high-frequency pulses, so it plays the role of blocking AC pulses with DC resistance.

SMD inductors are electromagnetic induction elements wound with insulated wires. Belongs to commonly used inductive components. The role of the chip inductor: DC resistance to AC. This is a simple statement. Isolate the AC signal, filter it or form a resonant circuit with capacitors, resistors, etc. The role of tuning and frequency selection inductors: the inductor coil and capacitor can form an LC in parallel. Tuning 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 through the chip inductor changes, the DC voltage potential generated in the chip inductor will prevent the current from changing. When the current through the inductive coil increases, the self-inductive electromotive force and electricity generated by the inductive coil decrease. When the current through the inductive coil decreases, the self-inductive electromotive force is in the same direction as the current. Compensation current reduction. The flow direction is reversed, preventing the current from increasing, and at the same time converting part of the electrical energy into magnetic field energy stored in the inductor; therefore, after filtering by the inductor, not only the load current and voltage ripples are reduced, the waveform becomes smooth, and the rectifier diode is turned on. The angle increases ^[1] .
