In recent years, benefiting from the rapid development of photovoltaic energy storage, new energy vehicles, and charging piles, magnetic components have grown rapidly. At present, although there are a large number of potential competitors in the new energy market, due to the fast product iteration speed and strict quality standards, there are currently few large-scale enterprises with batch supply for multiple new energy application scenarios. Recently, JBright, a solution provider specializing in EMC magnetic components, released a new type of LLC transformer.

With deep technology accumulation and continuous innovation spirit, Qichang Electronics has developed customized LLC transformers that can not only maintain the cutting-edge technology level, but also meet the needs of different scenarios:

1. Customized design for different scenarios to meet customer needs to the greatest extent

Qichang Electronics is well aware of the diverse needs of LLC transformers in different application scenarios. Whether it's in industrial automation equipment, in high-efficiency power modules in data centers, or in charging facilities for new energy vehicles, each area has unique power requirements.

Taking the field of industrial automation as an example, the equipment needs to operate stably in a complex electromagnetic environment, which requires extremely high anti-interference ability and reliability of LLC transformers. The customized LLC transformer developed by Qichang adopts a special shielding structure and optimized core material, which effectively reduces electromagnetic interference, ensures stable and accurate voltage and current output under harsh working conditions, and ensures the efficient operation of industrial automation production lines.2. Adopt cutting-edge integrated technology to greatly reduce the volume of products

Sakisho Electronics' LLC transformers can integrate resonant inductors and physical PFC inductors, which helps customers greatly reduce the size of their products.

3. R&D team composed of senior engineers and professional technicians

Through the integration of international top talent resources, Qichang Electronics has built a core team with both technical accumulation and practical experience. The team is composed of senior engineers and professional and technical personnel, and the main personnel of its design and development, production management and quality control departments are from Murata, Sumida, Sagami and other first-line manufacturers, and generally have more than 20 years of work experience in the field of magnetic components, forming a full chain of professional capabilities covering technological innovation, process optimization and quality assurance.

They delve into the characteristics of each industry, from the initial circuit design concept, to the careful selection of magnetic materials, to the strict control of the manufacturing process, every step of the process is excellent.

4. Introduce simulation technology into R&D to shorten the R&D cycle and improve cost performance

In the process of research and development, Qichang Electronics also actively introduces advanced simulation technology to predict and optimize the performance of LLC transformers in an all-round way through computer simulation. This not only greatly shortens the R&D cycle, but also identifies and solves potential problems at the design stage, providing customers with more cost-effective products.

In addition to LLC transformers, automotive common mode inductors are also one of the ace products of Qichang Electronics.

Qichang Electronics engineers have more than 20 years of experience in the design of magnetic components, and the design of common mode inductors comprehensively considers the needs of customers in terms of inductance, frequency, impedance, current and structure, and can also be customized for the specific common mode noise frequency encountered by customers.

In terms of material selection, Qichang selects high-performance magnetic materials, which have the characteristics of high permeability and low loss, and can effectively suppress common-mode interference signals. At the same time, in terms of structural design, the engineers carefully optimized the winding layout and magnetic circuit structure of the common mode inductor, reduced magnetic flux leakage, and improved the stability and reliability of the inductor.In order to ensure product quality, Qichang has established a strict quality control system. From the incoming inspection of raw materials, to the testing of each process in the production process, to the comprehensive performance testing of finished products, every link is strictly controlled. After countless experiments and verifications, the automotive common-mode inductor developed by Qichang has performed well in practical applications, which can effectively filter out electromagnetic interference in the on-board electronic system and provide a pure and stable electromagnetic environment for the electronic equipment of the car.
