Current transformer is an instrument that converts a large current on the primary side into a small current on the secondary side based on the principle of electromagnetic induction. The current transformer is composed of a closed core and windings. Its primary winding has a small number of turns and is strung in the circuit of the current that needs to be measured. The principle of current transformer is based on the principle of electromagnetic induction. The current transformer is composed of a closed core and windings. Its primary winding has very few turns and is connected in series in the line where the current needs to be measured. Therefore, it often has all the current of the line flowing through it. Its secondary winding has more turns and is connected in series in the measuring instrument and protection circuit. The current mutual inductance When the transformer is working, its secondary circuit is always closed, so the impedance of the series coil of the measuring instrument and the protection circuit is very small, and the working state of the current transformer is close to the short circuit.
Common mode chokes, or common mode inductors, consist of two or more coils of insulated wire on a single magnetic core. Each winding is put in series with one of the conductors. This means that the magnetic fields of the wires combine to present high impedance to the noise signal. Common mode choke is an inductive device used to suppress common mode interference signals. Its main features are that it can suppress common-mode interference signals, realize differential mode conversion, have large inductance value, and small size. Common mode inductors can be used in power supply, communications, computers, medical care, industrial automation and other fields. It is often used in computer switching power supplies to filter common mode electromagnetic interference signals. In the computer field, common mode inductors are widely used in network communications, servers, data centers and other places. In these places, common-mode inductors can effectively suppress common-mode noise on power lines or signal lines, ensuring the stability and integrity of data transmission. In addition to the computer field, common mode inductors have also found wide applications in automotive electronics, medical equipment, industrial control and other fields. In these situations, common mode inductors can also play a role in suppressing common mode interference and improving signal quality. In the field of automotive electronics, common mode inductors are used to suppress common mode noise on automotive power lines to ensure stable operation of automotive control systems. In the field of medical equipment, common mode inductors can be used to suppress electromagnetic interference on the power lines of medical equipment, thereby improving the electrical performance and reliability of medical equipment. In the field of industrial control, common mode inductors can be used to suppress common mode noise on signal lines in industrial control systems, thereby improving the accuracy and stability of the control system.
Magnetic integrated transformer refers to a miniature transformer manufactured using integrated circuit technology, which integrates coils and iron cores. It has unique characteristics such as small size and lightweight. Compared with traditional iron core transformers, magnetic integrated transformers can not only reduce current loss and magnetic loss, but also have the advantages of more precise voltage regulation, lower noise and higher energy efficiency. Therefore, magnetic integrated transformers have become one of the technologies worth promoting in industries such as power networks and new energy. With the continuous development of new energy technology, magnetic integrated transformers have also been widely used in the field of new energy. For example, in wind power generation systems, the use of magnetic integrated transformers can not only improve the stability of wind turbine speed regulation, but also eliminate harmonic interference. In addition, the high efficiency and miniaturization characteristics of magnetic integrated transformers have also been widely used in power conversion and battery management systems in electric vehicle charging stations. Compared with traditional transformer technology, magnetic integrated transformers have the following significant advantages in the field of new energy: 1. Small size and light weight: Magnetic integrated transformers can achieve a significant reduction in volume and weight while ensuring the same power transmission capacity, which is conducive to wide application in new energy applications with limited space. 2. High efficiency and low loss: Magnetic integrated transformers have the advantages of higher energy efficiency and smaller current loss and magnetic loss, which can greatly improve the operating efficiency of new energy systems. 3. Precise voltage regulation: Magnetic integrated transformers have more precise voltage regulation characteristics, which is beneficial to voltage stability control in new energy situations. At present, the application of magnetic integrated transformers in the field of new energy is still in its infancy, but its unique advantages and broad application prospects will make it more popular and in-depth used in the future. Magnetic integrated transformers will continue to play an important role in reducing power transmission energy consumption, improving system efficiency, and improving power quality in the future, and are expected to play an increasingly important role in the transformation of new energy.
MAIKE is specialized in the design and manufacture of high-quality customized planar transformers and inductors. The factory is based in Mianyang which is the only National Science & Technology city in China and is strategically placed to service the global electronics market. We design and manufacture for a variety of end-user applications ranging from Welding to Aerospace & Automotive & Battery Charging etc. The planar transformer is a transformer with high frequency, low profile, small height, and high operating frequency. Compared with conventional transformers, the size of the magnetic core of planar transformers is greatly reduced, especially when the height is reduced the most. This feature is very attractive in power supply equipment where space is strictly limited, making it the preferred magnetic component in many power supply equipment. The structural advantages of planar transformers also bring many advantages to its electrical characteristics: high power density, high efficiency, low leakage inductance, good heat dissipation, and low cost. Key Features-- (1) High current density. The wires of a planar transformer are actually planar conductors, so the current density is high. (2) High efficiency. The efficiency can reach 98%~99%. (3) Low leakage inductance. Approximately 0.2% of the primary inductance. (4) Good heat conduction. The hot aisle distance is short and the temperature rise is low. (5) Low EMI radiation. Good core shielding can keep radiation to a very low level. (6) Small size. The use of a small magnetic core can reduce the size accordingly. (7) The parameters have good repeatability. Because the winding structure is fixed and easy to pre-process, the parameters are stable. (8) Wide operating frequency range. The frequency can be from 50kHz to 2MHz. (9) Wide operating temperature range. The working temperature is -40 130. (10) Good insulation. The planar transformer is composed of overlapping conductive circuits and insulating sheets, thereby ensuring up to 4 kV insulation isolation between windings, primary-secondary and secondary-secondary.
