SMD Shielded Power Inductors in DC-DC Converter Circuits
SMD shielded power inductors are also widely used in electronic circuits. They can not only provide the necessary power circuit and voltage conversion functions but also effectively reduce electromagnetic interference through their shielding design, thereby ensuring the stability and reliability of the circuit.
The application of SMD shielded power inductors in DC-DC converters mainly includes the following aspects:
1. DC/DC converters for laptop CPUs: SMD shielded power inductors play a key role in DC/DC converters for laptop CPUs, providing stable current and voltage to ensure the normal operation of the CPU.
2. Mobile phones: In smartphones, SMD shielded power inductors are used in various power management circuits to help reduce electromagnetic interference and improve the stability and reliability of the equipment.
3. Liquid crystal display (LCD): In LCD devices, SMD shielded power inductors are used for power management to ensure stable power supply of the display and reduce electromagnetic interference.
4. Hard disk drive (HDD): In the power management of hard disk drives, SMD shielded power inductors provide stable current and voltage to ensure the normal operation of the hard disk.
5. Servers: In servers, SMD shielded power inductors are used in power modules to ensure stable power supply of servers and reduce electromagnetic interference, improving the overall performance of servers.
SMD shielded power inductors have the following features:
Magnetic shielding structure: minimizes electromagnetic interference (EMI) and ensures circuit stability.
Low DC resistance (DCR): reduces energy loss and improves efficiency.
High-rated current: can withstand large current loads and is suitable for high-power applications.
SMD shielded power inductors for DC-DC converters have many important functions in the circuit, mainly including the following aspects:
1. Energy storage and release: SMD shielded power inductors can store the electrical energy provided by the power supply and release this energy when needed, which is essential for maintaining the stable operation of the circuit.
2. Reduce electromagnetic interference: The shielding design can effectively block the magnetic field generated inside the inductor from radiating outward, while reducing the impact of external electromagnetic interference on the inside of the inductor, thereby improving the anti-interference ability of the circuit.
3. Improve power efficiency: By reducing energy loss, the shielding design can improve the efficiency of power conversion, thereby improving the overall power efficiency of the circuit.
4. Filtering effect: Power inductors can filter out the AC component in the current and make the output voltage more stable. In electronic circuits, this helps to reduce the ripple in the power supply, improve the purity of the power supply, and provide a stable DC voltage for electronic equipment.
5. Energy conversion: In circuits such as switching power supplies, power inductors can convert input voltage into output voltage to meet the needs of different electronic devices. For example, in a DC-DC converter, the power inductor converts the input DC voltage into an output voltage of different voltage levels by continuously storing and releasing energy.
6. Electromagnetic interference suppression: Since the inductor coil has impedance characteristics, the power inductor can effectively suppress the propagation of electromagnetic interference signals and improve the reliability and stability of the equipment.
7. Current limitation: The power inductor can limit the current to prevent excessive current from damaging the circuit. When the current exceeds the set value, the inductor coil will produce a larger impedance, thereby limiting the increase in current.
8. Choking effect: Prevent the sharp change of current in the AC circuit, so that the current passes through the circuit relatively smoothly to ensure the normal operation of the circuit.
9. Tuning and frequency selection effect: The inductor coil and the capacitor in parallel can form an LC oscillator, which plays a tuning and frequency selection role to ensure that the circuit works normally at a specific frequency.
These functions together ensure the stable and efficient operation of DC-DC converters in various electronic devices. In DC-DC converters, SMD shielded power inductors are mainly used to store and release energy, reduce electromagnetic interference, and improve the power efficiency of the circuit. Its shielding design can effectively block the internal magnetic field from radiating outward, reduce the impact of external electromagnetic interference on the inductor, and thus improve the stability and efficiency of the circuit.
