We produce Encapsulated Transformer, High frequency switching transformer, Low frequency power transformer ,inductor and current transformer.
A High Frequency Switching Transformer is used in electrical power transmission. It can have three different types of circuits: half-bridge, full-bridge, and push-pull. Generally, a transformer's circuits are symmetrical. This means that there is a 50:50 ratio between the positive and negative half-cycle excitation currents. The magnetic flux density Bs varies symmetrically from side to side in the transformer core. The maximum change range is around 2Bm.
A High Frequency Switching Transformer can also have three types of wires. The first two types of wires are made of copper. The third type of wire is made of copper-alloy wire or tin-plated copper wire. It has a cross-sectional area of between 0.032 mm2 and 0.20 mm2.
High-frequency switching transformers are available in a variety of sizes and specifications. Yuan Dean offers several types of high-frequency transformers for various applications. These high-frequency transformers meet RoHS compliance standards and can be customized to meet customer requirements. And with their patented technology, they can push the boundaries of high-power power conversion.
The primary and secondary windings are wound onto the same iron core. This core provides a path for the flux to travel through. The core is made of a high-permeable material to reduce the flux loss. With better core construction techniques, the flux lines can be confined within the core to increase its efficiency.
Various methods have been used to minimize the size and weight of the high-frequency switching transformer. One method has been used to reduce the skin effect caused by high-frequency currents. This method is known as Litz wire and consists of multiple smaller conductors that are woven together. The size and number of strands used depend on the frequency. Higher frequencies require smaller strands while lower frequencies need larger ones.
Another method is the asymmetric winding arrangement. This method allows for controlled leakage inductance and is able to maximize efficiency in dual-active bridge converters. It utilizes a coupled electromagnetic analysis model. In addition, the model is verified with experimental data. This method can also be used to improve the design of a high-frequency transformer.
High frequency switching transformers operate at frequencies much higher than line voltage transformers. They range from 20 KHz to over 1MHz. This means that they can be smaller than line voltage transformers. In addition, they can also operate at higher temperatures and have better power characteristics. These properties make them an excellent choice for high-frequency power-switching applications.
Besides providing dc-to-dc voltage conversion, these transformers also have a high-frequency regulation function. In addition, they are lightweight and highly efficient. A compact high-frequency transformer can be designed with a high voltage of 20 kHz and a low-cut-off frequency of A+-0.6 T.
Bidirectional DC-DC converters are becoming increasingly popular, and their use is growing, particularly in renewable energy sources and electric vehicles. The three-state switching cell used in novel DC-DC converter topologies reduces the size and cost of magnetic components. It also improves the distribution of losses in the converter.
