We produce Encapsulated Transformer, High frequency switching transformer, Low frequency power transformer ,inductor and current transformer.
The general purpose of an inductor is to store energy in a magnetic field when electrical current flows through it. Inductors are passive electrical components that are used in various applications within electrical and electronic circuits due to their ability to resist changes in current. Here are the key functions and purposes of inductors:
Key Functions and Purposes of Inductors:
Energy Storage:
Magnetic Field: Inductors store energy in the form of a magnetic field created by the current passing through their coils.
Temporary Storage: This energy storage capability is often used in power supplies and converters to temporarily store energy and release it when needed.
Filtering:
Signal Filtering: Inductors are used in filters (such as low-pass, high-pass, band-pass, and band-stop filters) to allow certain frequencies to pass while blocking others.
Noise Suppression: They can filter out noise or unwanted signals from power lines and signal lines.
Impedance Matching:
Tuning Circuits: In radio frequency (RF) applications, inductors are used in tuning circuits to match the impedance of different circuit elements, improving signal transfer and minimizing reflection.
Choke:
Current Choking: Inductors, often called chokes, are used to limit or "choke" high-frequency AC signals while allowing DC or lower-frequency AC signals to pass.
Power Supply Filtering: In power supplies, chokes help in smoothing out the rectified AC current to produce a stable DC output.
Transformers:
Energy Transfer: Inductors are the primary components of transformers, which transfer energy between circuits through electromagnetic induction.
Voltage Conversion: Transformers use inductors to step up or step down voltage levels in power distribution systems.
Inductive Reactance:
AC Circuits: In AC circuits, inductors provide reactance, which opposes changes in current. This property is used in various applications to control the phase and amplitude of AC signals.
Specific Applications:
Power Supplies: Inductors are used in switch-mode power supplies (SMPS) to regulate and filter the output voltage.
Audio Equipment: Inductors are part of crossover networks in speakers, separating different frequency ranges for different drivers (e.g., tweeters, woofers).
RF and Communication: Inductors are used in RF circuits for tuning and impedance matching.
Automotive: Inductors are used in automotive ignition systems and various electronic control units (ECUs).
Inductors are versatile components used primarily for their ability to store energy in a magnetic field, filter signals, match impedance, and choke unwanted signals. Their applications span across power supplies, audio equipment, RF circuits, and many other electronic systems.
